Structure of deformed w1+∞ symmetry and topological generalization in Celestial CFT
Abstract
We investigate a deformation of w1+∞ algebra recently introduced in [1] in the context of Celestial CFT that we denote by W˜1+∞ algebra. We obtain the operator product expansions of the generating currents of this algebra and explore its supersymmetric and topological generalizations.
