Title: Koszul duality for algebras

Zoom: https://uregina-ca.zoom.us/j/99127226830?pwd=bnFQR1R3UUdyWUxqSS9JMExMRlZwZz09

Abstract:  

If an algebra A is Koszul, certain subcategories of the derived categories of graded A-modules and A^!-modules form an equivalence. In this talk, I will discuss what it means for an algebra to be Koszul, the Koszul dual of a quadratic algebra, and will focus on some examples (the symmetric algebra and exterior algebra being Koszul dual to each other).
