Title:Nearby cycle of arithmetic D-modules and some applications
Time&Venue: 2025年4月23日（星期三） 14:00-15:00 、15:30-16:30 & 晨兴110
Abstract: Arithmetic D-module is the 6-functor formalism for a p-adic cohomology for varieties over field of positive characteristic, introduced by Berthelot.
Thanks to the works of Berthelot, Caro and others, most of the foundations has been laid.Even though I introduced nearby cycle functor some years ago, there are still some deficits.I want to discuss the theory of nearby cycles and arithmetic D-module theory for formal schemes.The first talk is mainly the review of the theory, and at the end of the second talk, I want to give some applications to the algebraicity of diagonal sequence.The talk is partly a joint work with R. Crew.
