Topic: 

Localization in Khovanov Homology

Description: 

For periodic links, we show that the Khovanov space of Lipshitz-Sarkar admits a natural cyclic group action, and identify its fixed point set. As an application, we prove that the Khovanov homology (with coefficients in the field of p elements) of a p-periodic link has rank greater than or equal to that of the annular Khovanov homology of the quotient link. This talk includes joint work with Aaron Mazel-Gee, Mike Willis, and Melissa Zhang.
