A survey of equivariant operations on quantum cohomology for symplectic manifolds (2409.01743v2)

Abstract: In this survey paper, we will collate various different ideas and thoughts regarding equivariant operations on quantum cohomology (and some in more general Floer theory) for a symplectic manifold. We will discuss a general notion of equivariant quantum operations associated to finite groups, in addition to their properties, examples, and calculations. We will provide a brief connection to Floer theoretic invariants. We then provide abridged descriptions (as per the author's understanding) of work by other authors in the field, along with their major results. Finally we discuss the first step to compact groups, specifically $S^1$-equivariant operations. Contained within this survey are also a sketch of the idea of mod-$p$ pseudocycles, and an in-depth appendix detailing the author's understanding of when one can define these equivariant operations in an additive way.
