Abstract
Given a constructible sheaf on a complex manifold, Kashiwara-Schapira defined the notion of singular support and characteristic cycle of . On the other hand for a Zariski constructible \'{e}tale sheaf on an algebraic variety , Beilinson defined the notion of singular support of and Saito defined the notion of characteristic cycle of . In this article we compare these notions and prove that they agree in a suitable sense. In the appendix we discuss extension of the notions of singular support and characteristic cycles developed by Umezaki-Yang-Zhao and Barrett.
