SB.GetRing
Returns the superring of a given subalgebra.
Syntax
SB.GetRing(S: TAGGED(<quotes>$apcocoa/sagbi.Subalgebra</quotes>)): RING
Description
This function returns the superring of a given subalgebra S, i.e. the ring R which S is a subalgebra of.
@param S A subalgebra
@return The superring of S
Example
Use R ::= QQ[x,y,z]; S := SB.Subalgebra(R,[x^2,y+z]); PrintLn SB.GetRing(S); -- RingWithID(1217, <quotes>QQ[x,y,z]</quotes>)
