A conjectural chain model for positive $S^1$-equivariant symplectic homology of star-shaped toric domains in $\mathbb{C}^2$

Abstract

For any star-shaped toric domain in $\mathbb{C}^2$, we define a filtered chain complex which conjecturally computes positive $S^1$-equivariant symplectic homology of the domain. Assuming this conjecture, we show that the limit $\lim_{k \to \infty} c^{\mathrm{GH}}_k(X)/k$ exists for any star-shaped toric domain $X \subset \mathbb{C}^2$, where $c^{\mathrm{GH}}_k$ denotes the $k$-th Gutt-Hutchings capacity.
