On the comparison of nearby cycles via $b$-functions

Abstract

In this article, we give a simple proof of the comparison of nearby and vanishing cycles in the sense of Riemann-Hilbert correspondence following the idea of Beilinson and Bernstein, without using the Kashiwara-Malgrange VV-filtrations.
