Structure of deformed $w_{1+\infty }$ symmetry and topological generalization in Celestial CFT

Pavel Drozdov, Taro Kimura

We investigate a deformation of $w_{1+\infty }$ algebra recently introduced in arxiv:2111.11356 in the context of Celestial CFT that we denote by ${\tilde{W}}_{1+\infty }$ algebra.…
