概要
We give an algorithm for computing multiplier ideals using Gr\"obner bases in Weyl algebras. To do it, we introduce a variant of (generalized)
Bernstein--Sato polynomials defined by Budur--Mustata--Saito and give an algorithm for computing it. We present several examples computed by our algorithm.
