Computes the multiplier ideal of I with coefficient t using Howald's Theorem and the package Normaliz.
i1 : R = QQ[x,y];
i2 : I = monomialIdeal(y^2,x^3);
o2 : MonomialIdeal of R
i3 : monomialMultiplierIdeal(I,5/6)
Warning: Cone could not compute everything, that it was asked for!
Missing: Multiplicity
o3 = monomialIdeal (x, y)
o3 : MonomialIdeal of R
