Abstract:  Involutive Heegaard Floer homology has recently seen a lot of use in low-dimensional topology, getting at information not visible to its non-equivariant relatives.  In this talk, we discuss a surgery formula for involutive Floer homology, and as an application construct many interesting classes in the 3-dimensional homology cobordism group.  This is joint work with Kristen Hendricks, Jen Hom, and Ian Zemke.
