Demonstration constructive de l'existence de polynomes de Bernstein-Sato pour plusieurs fonctions analytiques
arXiv:math/0307179
Abstract
In 1987, C. Sabbah proved the existence of Bernstein-Sato polynomials associated with several analytic functions. The purpose of this article is to give a more elementary and constructive proof of the result of C. Sabbah based on the notion of the analytic Grobner fan of a D-module.
