inv -- A method for computing the reduced inverse ideal

Synopsis

Description

The function inv computes the inverse reduced ideal given an integral ideal

o1 = R

o1 : PolynomialRing
i2 : I=qR(R,y^2-x^3-7*x)

o2 = I

o2 : QuotientRing
i3 : J=ideal(x,y);inv(J)

o3 : Ideal of I

o4 = ideal (x, y)

o4 : Ideal of I
