Abstract
In \cite{MR1957829}, Ozsváth and Szabó use Heegaard Floer homology to define numerical invariants and for 3-manifolds with . We define involutive Heegaard Floer theoretic versions of these invariants analogous to the involutive invariants and defined for rational homology spheres by Hendricks and Manolescu in \cite{MR3649355} . We prove their invariance under spin integer homology cobordism and use them to establish spin filling constraints and -surgery obstructions analogous to results by Ozsváth and Szabó for their Heegaard Floer counterparts and . We then apply calculation techniques of Dai and Manolescu developed in \cite{MR4021102} and Rustamov in \cite{Rustamov} to compute the involutive Heegaard Floer homology of some negative semi-definite plumbed 3-manifolds with . By combining these calculations with the -surgery obstructions, we are able to produce an infinite family of small Seifert fibered spaces with weight 1 fundamental group and first homology which cannot be obtained by -surgery on a knot in , extending a result of Hedden, Kim, Mark, and Park in \cite{MR4029676}.
