Special Lecture Series on Derived Algebraic/Differential Geometry

02/05/2019 3:00 pm - 05/09/2019 4:30 pm


In the Spring 2019 Semester, the CMSA will be hosting a special lecture series on Derived algebraic/differential geometry run by Artan Sheshmani, with lectures given by Prof. Sheshmani and Dr. Dennis Borisov. The seminar will be held on Tuesdays and Thursdays from 3:00-4:30pm in CMSA, room G10.

Section 1: Basic setting of derived geometry

The goal: To collect the minimum set of tools needed to do algebraic geometry in the derived context.
