Riemann--Hilbert correspondence for irregular holonomic $\mathscr{D}$-modules
M. Kashiwara
Abstract: This is a survey paper on the Riemann--Hilbert correspondence on (irregular) holonomic $\mathscr{D}$-modules, based on the 16th Takagi Lectures (2015/11/28). In this paper, we use subanalytic sheaves, an analogous notion to the one of indsheaves.
