We'll sketch the definition of the involutive Heegaard Floer homology constructed by Hendricks-Manolescu, and then explain how this homology theory behaves under surgery. As a consequence, we can use the surgery formula to construct three-manifolds which are not homology cobordant to any combination of Seifert fiber spaces. This is joint work Kristen Hendricks, Jen Hom and Ian Zemke.
