Query: Existence of Bernstein-Sato polynomials by using the analytic Grobner
  fan   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 Gr\"obner fan of a D-module.
