Categorification of the elliptic Hall algebra

Quantum Algebra 2025-05-14 v1 Representation Theory

Abstract

We show that the central charge kk reduction of the universal central extension of the elliptic Hall algebra is isomorphic to the trace, or zeroth Hochschild homology, of the quantum Heisenberg category of central charge kk. As an application, we construct large families of representations of the universal extension of the elliptic Hall algebra.
