Topic: 

Constructing a Smith-type inequality in knot Floer homology

Description: 

A Smith inequality refers to a rank inequality between the homology of a space with a G action and the homology of its fixed set. In the case of G = Z/2, I will discuss an analog of this statement for the Knot Floer homology of periodic knots, including a conjectural filtered refinement. These inequalities appear to give new restrictions on the Alexander polynomials of periodic alternating and periodic L-space knots.
