CASA Function: generators

Returns the generators of an algebraic set.

Calling Sequence:

• r := generators(A)

Parameters:

a : algset

• An algebraic set.

Result:

r : {list(polynom),list(ratpoly),list(list(polynom),list(ratpoly)),procedure}

• The algebraic objects representing the algebraic set A.

Description:

• The function returns the algbraic objects which represent an algebraic set, i.e. for implicit representation: the list of polynomials; parametric representation: the list of rational functions; projected representation: [list of polynomials, list of rational functions]; representation by places: list of list of power series.

Examples:

> A := mkProjAlgSet([[u^2-v^3+v^2],[u+v,u-v,1/v]],[u,v]);

> generators(A);
