Braid group actions from categorical symmetric Howe duality on deformed Webster algebras

Quantum Algebra 2024-01-22 v2

Abstract

We construct a 2-representation categorifying the symmetric Howe representation of glm\mathfrak{gl}_m using a deformation of an algebra introduced by Webster. As a consequence, we obtain a categorical braid group action taking values in a homotopy category.
