Speaker: Mauro Porta (U of Strasbourg)
Title: Virtual classes in analytic geometry
Date (JST): Thu, Nov 15, 2018, 15:30 - 17:00
Place: Seminar Room A
Abstract: In this talk I will survey ongoing work with T. Y. Yu. In the first introductory part of the talk I will explain general motivations that lead to consider virtual classes and I will give examples arising from different areas. I will also explain how derived geometry can be successfully used to construct and sometimes compute virtual classes in these situations. In the second part of the talk, I will focus on the analytic aspects of the theory. I will review the main foundational results of derived analytic geometry and I will survey recent progresses in my joint work with T. Y. Yu on the construction of non-archimedean Gromov-Witten invariants.
