| 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. |
