Coulomb branch algebras via symplectic cohomology
Abstract
Abstract Let be a compact symplectic manifold with convex boundary and . Suppose that is equipped with a convex Hamiltonian ‐action for some connected, compact Lie group . We construct an action of the pure Coulomb branch of on the ‐equivariant symplectic cohomology of . Building on work of Teleman ( J. Eur. Math. Soc . 23 (2021), 3497–3520), we use this construction to characterize the Coulomb branches of Braverman–Finkelberg–Nakajima ( Adv. Theor. Math. Phys . 22 (2018), 1071–1147) in terms of equivariant symplectic cohomology.
