# Matt Stoffregen, MIT – Triangle Topology Seminar

**Location:** 332 Phillips Hall, 4:30 pm – 5:30 pm

**Speaker:** Matt Stoffregen, MIT

**Title:** *Localization in Khovanov Homology*

**Abstract:** 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 is joint work with Melissa Zhang.
