Computing involutive HF-hat

Hendricks-Manolescu's "involutive Heegaard Floer homology"

is a variant of Heegaard Floer homology which capitalizes on the conjugation action on spin^c structures. In this talk we will discuss an algorithm for computing the simplest version of involutive Heegaard Floer homology, involutive HF-hat.  This is joint work with Kristen Hendricks, and builds on earlier joint work with Peter Ozsváth and Dylan Thurston.
