SubalgebraBases :: generators(SAGBIBasis)

generators(SAGBIBasis) -- Returns a partial sagbi generating set

Synopsis

Function: generators
Usage:

result = gens S
Inputs:
- S, an instance of the type SAGBIBasis,
Optional inputs:
- CoefficientRing => a Boolean value, default value null, used option
Outputs:
- result, a matrix,

Description

Returns a generating set for the original Subring. The output is slightly different, depending on the state of S.

No sagbi generators: returns the generators of the original subring
Partial sagbi basis: subducts the generators of the original subring by the partial sagbi basis and returns the concatenation of the partial sagbi basis and the result of the subduction.
Finite sagbi basis: returns the sagbi basis
