Capacities from the Chiu-Tamarkin complex

Symplectic Geometry 2024-10-24 v5

Abstract

In this paper, we construct a sequence (ck)kN(c_k)_{k\in\mathbb{N}} of symplectic capacities based on the Chiu-Tamarkin complex CT,C_{T,\ell}, a Z/\mathbb{Z}/\ell-equivariant invariant coming from the microlocal theory of sheaves. We compute (ck)kN(c_k)_{k\in\mathbb{N}} for convex toric domains, which are the same as the Gutt-Hutchings capacities. Our method also works for the prequantized contact manifold TX×S1T^*X\times S^1. We define a sequence of "contact capacities" ([c]k)kN([c]_k)_{k\in\mathbb{N}} on the prequantized contact manifold TX×S1T^*X\times S^1, and we compute them for prequantized convex toric domains.
