Algorithm for computing local Bernstein-Sato ideals

Abstract

Given $p$ polynomials of $n$ variables over a field $k$ of characteristic 0 and a point $a\in k^n$, we propose an algorithm computing the local Bernstein-Sato ideal at $a$. Moreover with the same algorithm we compute a constructible stratification of $k^n$ such that the local Bernstein-Sato ideal is constant along each stratum. Finally, we present non-trivial examples computed with our algorithm.
