Matt Stoffregen, MIT – Triangle Topology Seminar

September 25, 2018 @ 4:30 pm - 5:30 pm

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.
