2215`Differential extensions of a ring \spad{R}. Given a differentiation on \spad{R},{} extend it to a differentiation on \%.
2275`\spadtype{DifferentialPolynomialCategory} is a category constructor specifying basic functions in an ordinary differential polynomial ring with a given ordered set of differential indeterminates. In addition,{} it implements defaults for the basic functions. The functions \spadfun{order} and \spadfun{weight} are extended from the set of derivatives of differ

Other operations provided on differential polynomials are \spadfun{leader},{} \spadfun{initial},{} \spadfun{separant},{} \spadfun{differentialVariables},{} and \spadfun{isobaric?}. Furthermore,{} if the ground ring is a differential ring,{} then evaluation (substitution of differential indeterminates by elements of the ground ring or by differential polynomials) is provided by \spadfun{eval}. A convenient way of referencing derivati
2275`--ves is provided by the functions \spadfun{makeVariable}. \blankline To construct a domain using this constructor,{} one needs to provide a ground ring \spad{R},{} an ordered set \spad{S} of differential indeterminates,{} a ranking \spad{V} on the set of derivatives of the differential indeterminates,{} and a set \spad{E} of exponents in bijection with the set of differential monomials in the given differential indeterminates. \blankline
2420`An ordinary differential ring,{} that is,{} a ring with an operation \spadfun{differentiate}. \blankline
2469`\spadtype{DifferentialVariableCategory} constructs the set of derivatives of a given set of (ordinary) differential indeterminates. If \spad{x},{} ...,{} \spad{y} is an ordered set of differential indeterminates,{} and the prime notation is used for differentiation,{} then the set of derivatives (including zero-th order) of the differential indeterminates is \spad{x},{} \spad{x'},{} \spad{x''},{} ...,{} \spad{y},{} \spad{y'},{}
2469`-- \spad{y''},{} ... (Note: in the interpreter,{} the \spad{n}-th derivative of \spad{y} is displayed as \spad{y} with a subscript \spad{n}.) This set is viewed as a set of algebraic indeterminates,{} totally ordered in a way compatible with differentiation and the given order on the differential indeterminates. Such a total order is called a ranking of the differential indeterminates. \blankline A domain in this category is needed to construct a differential polynomial domain. Differential poly
2469`--nomials are ordered by a ranking on the derivatives,{} and by an order (extending the ranking) on on the set of differential monomials. One may thus associate a domain in this category with a ranking of the differential indeterminates,{} just as one associates a domain in the category \spadtype{OrderedAbelianMonoidSup} with an ordering of the set of monomials in a set of algebraic indeterminates. The ranking is specified through the binary relation \spadfun{<}. For example,{} one may define on
2469`--e derivative to be less than another by lexicographically comparing first the \spadfun{order},{} then the given order of the differential indeterminates appearing in the derivatives. This is the default implementation. \blankline The notion of weight generalizes that of degree. A polynomial domain may be made into a graded ring if a weight function is given on the set of indeterminates,{} Very often,{} a grading is the first step in ordering the set of monomials. For differential polynomial do
2469`--mains,{} this constructor provides a function \spadfun{weight},{} which allows the assignment of a non-negative number to each derivative of a differential indeterminate. For example,{} one may define the weight of a derivative to be simply its \spadfun{order} (this is the default assignment). This weight function can then be extended to the set of all differential polynomials,{} providing a graded ring structure.

2932`An eltable over domains \spad{D} and \spad{I} is a structure which can be viewed as a function from \spad{D} to \spad{I}.

3607`FiniteAlgebraicExtensionField {\em F} is the category of fields which are finite algebraic extensions of the field {\em F}. If {\em F} is finite then any finite algebraic extension of {\em F} is finite,{} too. Let {\em K} be a finite algebraic extension of the finite field {\em F}. The exponentiation of elements of {\em K} defines a \spad{Z}-module structure on the multiplicative group of {\em K}. The additive group of {\em K} becomes
3607`-- a module over the ring of polynomials over {\em F} via the operation \spadfun{linearAssociatedExp}(a: \spad{K},{} \spad{f:} SparseUnivariatePolynomial \spad{F}) which is linear over {\em F},{} \spadignore{i.e.} for elements {\em a} from {\em K},{} {\em c,{} d} from {\em F} and {\em f,{} g} univariate polynomials over {\em F} we have \spadfun{linearAssociatedExp}(a,{} cf+dg) equals {\em c} times \spadfun{linearAssociatedExp}(a,{} \spad{f}) plus {\em d} times \spadfun{linearAssociatedExp}(a,{} 
3607`--\spad{g}). Therefore \spadfun{linearAssociatedExp} is defined completely by its action on monomials from {\em F[X]}: \spadfun{linearAssociatedExp}(a,{} monomial(1,{} \spad{k})\spad{\$}SUP(\spad{F})) is defined to be \spadfun{Frobenius}(a,{} \spad{k}) which is {\em a^(q^k)} where {\em q=size()\$F}.

25763`\spadtype{Float} implements arbitrary precision floating point arithmetic. The number of significant digits of each operation can be set to an arbitrary value (the default is 20 decimal digits). The operation \spad{float(mantissa,{} exponent,{} \spadfunFrom{base}{FloatingPointSystem})} for integer \spad{mantissa},{} \spad{exponent} specifies the number \spad{mantissa * \spadfunFrom{base}{FloatingPointSystem} ^ exponent} The underlying represent
25763`--ation for floats is binary not decimal. The implications of this are described below. \blankline The model adopted is that arithmetic operations are rounded to to nearest unit in the last place,{} that is,{} accurate to within \spad{2^(-\spadfunFrom{bits}{FloatingPointSystem})}. Also,{} the elementary functions and constants are accurate to one unit in the last place. A float is represented as a record of two integers,{} the mantissa and the exponent. The \spadfunFrom{base}{FloatingPointSystem
25763`--} of the representation is binary,{} hence a \spad{Record(m: mantissa,{} e: exponent)} represents the number \spad{m * 2 ^ e}. Though it is not assumed that the underlying integers are represented with a binary \spadfunFrom{base}{FloatingPointSystem},{} the code will be most efficient when this is the the case (this is \spad{true} in most implementations of Lisp). The decision to choose the \spadfunFrom{base}{FloatingPointSystem} to be binary has some unfortunate consequences. First,{} decimal
25763`-- numbers like 0.3 cannot be represented exactly. Second,{} there is a further loss of accuracy during conversion to decimal for output. To compensate for this,{} if \spad{d} digits of precision are specified,{} \spad{1 + ceiling(log2(10^d))} bits are used. Two numbers that are displayed identically may therefore be not equal. On the other hand,{} a significant efficiency loss would be incurred if we chose to use a decimal \spadfunFrom{base}{FloatingPointSystem} when the underlying integer base
25763`-- is binary. \blankline Algorithms used: For the elementary functions,{} the general approach is to apply identities so that the taylor series can be used,{} and,{} so that it will converge within \spad{O( sqrt n )} steps. For example,{} using the identity \spad{exp(x) = exp(x/2)^2},{} we can compute \spad{exp(1/3)} to \spad{n} digits of precision as follows. We have \spad{exp(1/3) = exp(2 ^ (-sqrt s) / 3) ^ (2 ^ sqrt s)}. The taylor series will converge in less than sqrt \spad{n} steps and the
25763`-- exponentiation requires sqrt \spad{n} multiplications for a total of \spad{2 sqrt n} multiplications. Assuming integer multiplication costs \spad{O( n^2 )} the overall running time is \spad{O( sqrt(n) n^2 )}. This approach is the best known approach for precisions up to about 10,{} 000 digits at which point the methods of Brent which are \spad{O( log(n) n^2 )} become competitive. Note also that summing the terms of the taylor series for the elementary functions is done using integer operation

40730`\spadtype{OrderlyDifferentialPolynomial} implements an ordinary differential polynomial ring in arbitrary number of differential indeterminates,{} with coefficients in a ring. The ranking on the differential indeterminate is orderly. This is analogous to the domain \spadtype{Polynomial}. \blankline
40931`\spadtype{OrderlyDifferentialVariable} adds a commonly used orderly ranking to the set of derivatives of an ordered list of differential indeterminates. An orderly ranking is a ranking \spadfun{<} of the derivatives with the property that for two derivatives \spad{u} and \spad{v},{} \spad{u} \spadfun{<} \spad{v} if the \spadfun{order} of \spad{u} is less than that of \spad{v}. This domain belongs to \spadtyp
40931`--e{DifferentialVariableCategory}. It defines \spadfun{weight} to be just \spadfun{order},{} and it defines an orderly ranking \spadfun{<} on derivatives \spad{u} via the lexicographic order on the pair (\spadfun{order}(\spad{u}),{} \spadfun{variable}(\spad{u})).
41027`This constructor produces an ordinary differential ring from a partial differential ring by specifying a variable.

42128`The domain \spadtype{PartialFraction} implements partial fractions over a euclidean domain \spad{R}. This requirement on the argument domain allows us to normalize the fractions. Of particular interest are the 2 forms for these fractions. The ``compact\spad{''} form has only one fractional term per prime in the denominator,{} while the \spad{``p}-adic\spad{''} form expands each numerator \spad{p}-adically via the prime \spad{p} in t
42128`--he denominator. For computational efficiency,{} the compact form is used,{} though the \spad{p}-adic form may be gotten by calling the function \spadfunFrom{padicFraction}{PartialFraction}. For a general euclidean domain,{} it is not known how to factor the denominator. Thus the function \spadfunFrom{partialFraction}{PartialFraction} takes as its second argument an element of \spadtype{Factored(R)}.

43222`This domain represents polynomial ideals with coefficients in any field and supports the basic ideal operations,{} including intersection,{} sum and quotient. An ideal is represented by a list of polynomials (the generators of the ideal) and a boolean that is \spad{true} if the generators are a Groebner basis. The algorithms u

There are two simplification routines: the first function \spadfun{idealSimplify} uses groebner basis of ideals alone,{} while the second,{} \spadfun{simplify} uses both groebner basis and factorization. The resulting defining equations \spad{L} always form a groebner basis,{} and the resulting defining inequation \spad{f} is al

50645`This domain exports a modest implementation of splitting trees. Spliiting trees are needed when the evaluation of some quantity under some hypothesis requires to split the hypothesis into sub-cases.

961671`This package is a suite of functions for the numerical integration of an ordinary differential equation of \spad{n} variables: \blankline \indented{8}{\center{dy/dx = \spad{f}(\spad{y},{} \spad{x})\space{5}\spad{y} is an \spad{n}-vector}} \blankline \par All the routines are based on a 4-th order Runge-Kutta kernel. These routines generally have as arguments: \spad{n},{} the number of dependent variables; \spad{x1},{} the initial point;
961671`-- \spad{h},{} the step size; \spad{y},{} a vector of initial conditions of length \spad{n} which upon exit contains the solution at \spad{x1 + h}; \spad{derivs},{} a function which computes the right hand side of the ordinary differential equation: \spad{derivs(dydx,{} y,{} x)} computes \spad{dydx},{} a vector which contains the derivative information. \blankline \par In order of increasing complexity: \begin{items} \blankline \item \spad{rk4(y,{} n,{} x1,{} h,{} derivs)} advances the solution 
961671`--vector to \spad{x1 + h} and return the values in \spad{y}. \blankline \item \spad{rk4(y,{} n,{} x1,{} h,{} derivs,{} t1,{} t2,{} t3,{} t4)} is the same as \spad{rk4(y,{} n,{} x1,{} h,{} derivs)} except that you must provide 4 scratch arrays \spad{t1}-\spad{t4} of size \spad{n}. \blankline \item Starting with \spad{y} at \spad{x1},{} \spad{rk4f(y,{} n,{} x1,{} x2,{} ns,{} derivs)} uses \spad{ns} fixed steps of a 4-th order Runge-Kutta integrator to advance the solution vector to \spad{x2} and r

The function takes two half steps and one full step and scales the difference in solutions at the final point. If the error is within \spad{eps},{} the step is taken and the result is retu

Upon input,{} an trial step size must be given and upon return,{} an estimate of the next step size to use is returned as well as the step size which produced the desired accuracy. The scaled error is computed as \center{\spad{error = MAX(ABS((y2steps(i) - y1step(i))/yscal(i)))}} and this is compared against \spad{eps}. If this is greater than \spad{e

Other operations provided on differential polynomials are \spadfun{leader},{} \spadfun{initial},{} \spadfun{separant},{} \spadfun{differentialVariables},{} and \spadfun{isobaric?}. Furthermore,{} if the ground ring is a differential ring,{} then evaluation (substitution of differential indeterminates by elements of the ground ring or by differential polynomials) is provided by \spadfun{ev
986334`--al}. A convenient way of referencing derivatives is provided by the functions \spadfun{makeVariable}. \blankline To construct a domain using this constructor,{} one needs to provide a ground ring \spad{R},{} an ordered set \spad{S} of differential indeterminates,{} a ranking \spad{V} on the set of derivatives of the differential indeterminates,{} and a set \spad{E} of exponents in bijection with the set of differential monomials in the given differential indeterminates. \blankline
986527`An ordinary differential ring,{} that is,{} a ring with an operation \spadfun{differentiate}. \blankline
986595`\spadtype{DifferentialVariableCategory} constructs the set of derivatives of a given set of (ordinary) differential indeterminates. If \spad{x},{} ...,{} \spad{y} is an ordered set of differential indeterminates,{} and the prime notation is used for differentiation,{} then the set of derivatives (including zero-th order) of the differential indeterminates is \spad{x},{} \spad{x'},{} \spad{x''},{
986595`--} ...,{} \spad{y},{} \spad{y'},{} \spad{y''},{} ... (Note: in the interpreter,{} the \spad{n}-th derivative of \spad{y} is displayed as \spad{y} with a subscript \spad{n}.) This set is viewed as a set of algebraic indeterminates,{} totally ordered in a way compatible with differentiation and the given order on the differential indeterminates. Such a total order is called a ranking of the differential indeterminates. \blankline A domain in this category is needed to construct a differential pol
986595`--ynomial domain. Differential polynomials are ordered by a ranking on the derivatives,{} and by an order (extending the ranking) on on the set of differential monomials. One may thus associate a domain in this category with a ranking of the differential indeterminates,{} just as one associates a domain in the category \spadtype{OrderedAbelianMonoidSup} with an ordering of the set of monomials in a set of algebraic indeterminates. The ranking is specified through the binary relation \spadfun{<}.
986595`-- For example,{} one may define one derivative to be less than another by lexicographically comparing first the \spadfun{order},{} then the given order of the differential indeterminates appearing in the derivatives. This is the default implementation. \blankline The notion of weight generalizes that of degree. A polynomial domain may be made into a graded ring if a weight function is given on the set of indeterminates,{} Very often,{} a grading is the first step in ordering the set of monomial
986595`--s. For differential polynomial domains,{} this constructor provides a function \spadfun{weight},{} which allows the assignment of a non-negative number to each derivative of a differential indeterminate. For example,{} one may define the weight of a derivative to be simply its \spadfun{order} (this is the default assignment). This weight function can then be extended to the set of all differential polynomials,{} providing a graded ring structure.

987321`An extensible aggregate is one which allows insertion and deletion of entries. These aggregates are models of lists and streams which are represented by linked structures so as to make insertion,{} deletion,{} and concatenation efficient. However,{} access to elements of these extensible aggregates is generally slow since access is made from the end. See \spadtype{FlexibleArray} for an exception.

987793`FiniteAlgebraicExtensionField {\em F} is the category of fields which are finite algebraic extensions of the field {\em F}. If {\em F} is finite then any finite algebraic extension of {\em F} is finite,{} too. Let {\em K} be a finite algebraic extension of the finite field {\em F}. The exponentiation of elements of {\em K} defines a \spad{Z}-module structure on the multiplicative group of {\em K}. The

Therefore \spadfun{linearAssociatedExp} is defined completely by its action on monomials from {\em F[X]}: \spadfun{linearAssociatedExp}(a,{} monomial(1,{} \spad{k})\spad{\$}SUP(\spad{F})) is defined to be \spadfun{Frobenius}(a,{} \spad{k}) which is {\em a^(q^k)} where {\em q=size()\$F}.

990492`\spadtype{JetBundleBaseFunctionCategory} defines the category of functions (local sections) of the base space of a jet bundle,{} \spadignore{i.e.} functions depending only on the independent variables. Such a category is needed \spadignore{e.g.} for the representation of solutions.
990609`\spadtype{JetBundleCategory} provides basic data structures and procedures for jet bundles. Nearly all necessary functions are implemented already here.

991122`A linear aggregate is an aggregate whose elements are indexed by integers. Examples of linear aggregates are strings,{} lists,{} and arrays.

994778`The category of regular triangular sets,{} introduced under the name regular chains in [1] (and other papers). In [3] it is proved that regular triangular sets and towers of simple extensions of a field are equivalent notions. In the following definitions,{} all polynomials and ideals are taken from the polyno
994778`--mial ring \spad{k[x1,{} ...,{} xn]} where \spad{k} is the fraction field of \spad{R}. The triangular set \spad{[t1,{} ...,{} tm]} is regular iff for every \spad{i} the initial of \spad{ti+1} is invertible in the tower of simple extensions associated with \spad{[t1,{} ...,{} \spad{ti}]}. A family \spad{[T1,{} ...,{} Ts]} of regular triangular sets is a split of Kalkbrener of a given ideal \spad{I} iff the radical of \spad{I} is equal to the intersection of the radical ideals generated by the sa
994778`--turated ideals of the \spad{[T1,{} ...,{} \spad{Ti}]}. A family \spad{[T1,{} ...,{} Ts]} of regular triangular sets is a split of Kalkbrener of a given triangular set \spad{T} iff it is a split of Kalkbrener of the saturated ideal of \spad{T}. Let \spad{K} be an algebraic closure of \spad{k}. Assume that \spad{V} is finite with cardinality \spad{n} and let \spad{A} be the affine space \spad{K^n}. For a regular triangular set \spad{T} let denote by \spad{W(T)} the set of regular zeros of \spad{
994778`--T}. A family \spad{[T1,{} ...,{} Ts]} of regular triangular sets is a split of Lazard of a given subset \spad{S} of \spad{A} iff the union of the \spad{W(\spad{Ti})} contains \spad{S} and is contained in the closure of \spad{S} (\spad{w}.\spad{r}.\spad{t}. Zariski topology). A family \spad{[T1,{} ...,{} Ts]} of regular triangular sets is a split of Lazard of a given triangular set \spad{T} if it is a split of Lazard of \spad{W(T)}. Note that if \spad{[T1,{} ...,{} Ts]} is a split of Lazard of 
994778`--\spad{T} then it is also a split of Kalkbrener of \spad{T}. The converse is \spad{false}. This category provides operations related to both kinds of splits,{} the former being related to ideals decomposition whereas the latter deals with varieties decomposition.

996421`The category of triangular sets of multivariate polynomials with coefficients in an integral domain. Let \spad{R} be an integral domain and \spad{V} a finite ordered set of variables,{} say \spad{X1 < X2 < ... < Xn}. A set \spad{S} of polynomials in \spad{R[X1,{} X2,{} ...,{} Xn]} is triangular if no elements of \spad{
996421`--S} lies in \spad{R},{} and if two distinct elements of \spad{S} have distinct main variables. Note that the empty set is a triangular set. A triangular set is not necessarily a (lexicographical) Groebner basis and the notion of reduction related to triangular sets is based on the recursive view of polynomials. We recall this notion here and refer to [1] for more details. A polynomial \spad{P} is reduced \spad{w}.\spad{r}.\spad{t} a non-constant polynomial \spad{Q} if the degree of \spad{P} in 
996421`--the main variable of \spad{Q} is less than the main degree of \spad{Q}. A polynomial \spad{P} is reduced \spad{w}.\spad{r}.\spad{t} a triangular set \spad{T} if it is reduced \spad{w}.\spad{r}.\spad{t}. every polynomial of \spad{T}. \newline
