Seminar on Crystalline Cohomology, Columbia 2018
This seminar met on Tuesdays from 4:30 - 6:00 in room 622. The seminar was organized by Brian Lawrence and Shizhang Li.
Crystalline cohomology is a p-adic cohomology theory for smooth, proper varieties in characteristic p. Our goal will be to understand the construction and basic properties of crystalline cohomology. Topics will depend on interest but may include the de Rham - Witt complex, rigid comohology or the interaction of Frobenius and the Hodge filtration.
