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.**
