U. Haifa Topology & Geometry seminar: Sunday, Mar. 27, 2022. Speaker: Oren Ben-Bassat (Haifa). Title: “Derived Analytic Geometry”.

Time: 17:15

Location: On Zoom and in Room 614 Haifa University Mathematics and Science Building


I will start by reviewing some work of others: sketching a (higher) categorical approach to geometry. After that, I will explain how using this approach (derived) analytic geometry can be viewed in a precise way as a type of algebraic geometry. I will explain and use in a fundamental way Banach rings and categories of Banach modules over a Banach ring.  The theories of derived analytic geometry from this perspective include both archimedean and non-archimedean analytic theories.  I will give examples of homotopy epimorphisms between algebras of analytic nature. I will include examples and relevance in the rigid analytic context and an arithmetic context. I will discuss descent theorems and time permitting, other topics such as blow-ups.
