This category represents the direct product of some set with respect to an ordered indexing set. The ordered set S is considered as the basis elements\ ``'' and the elements from A as coefficients\ ``''.

construct: List Record(k: S, c: A) -> %
construct(l) takes a list of terms and creates the object with these components.
constructOrdered: List Record(k: S, c: A) -> %
constructOrdered(l) takes a list of terms and creates the object with these components. The list is assumed to be sorted (in reverse order) with respect to the ordering of S. If R is a monoid, then the list is assumend to contain no zero elements. Caution: No checking is performed, so this should only be used in cases where those conditions are assured. If in doubt use construct.

leadingCoefficient: % -> A
leadingCoefficient(z) returns the coefficient of the leading (with respect to the ordering on the indexing set) monomial of z. Error: if z has no support.
leadingMonomial: % -> %
leadingMonomial(x) returns the monomial supported by the first element from S. Error: if x has no support.
leadingSupport: % -> S
leadingSupport(z) returns the index of leading (with respect to the ordering on the indexing set) monomial of z. Error: if z has no support.
leadingTerm: % -> Record(k: S, c: A)
leadingTerm(x) returns the leading (with respect to the ordering on the indexing set) term of z. Error: if z has no support.
listOfTerms: % -> List Record(k: S, c: A)
listOfTerms(x) returns a list lt of terms with type Record(k: S, c: R) such that x equals constructOrdered lt.
map: (A -> A, %) -> %
map(f, z) returns the new element created by applying the function f to each component of the direct product element z.

monomial: (A, S) -> %
monomial(a, s) constructs a direct product element with the s component set to a
monomial?: % -> Boolean
monomial?(x) returns true if x is a single monomial, that is support of x consists of a single element.
numberOfMonomials: % -> NonNegativeInteger
numberOfMonomials(x) returns the number of monomials of x.
opposite?: (%, %) -> Boolean if A has AbelianMonoid
from AbelianMonoid
reductum: % -> %
reductum(z) returns a new element created by removing the leading coefficient/support pair from the element z. Error: if z has no support.
