Sounds interesting

We would like to mention that a structure similar to categorical symmetry was found previously in AdS/CFT correspondence, [63–65] where a global symmetry $G$ at the high-energy boundary is related to a gauge theory of group $G$ in the low-energy bulk. In this paper, we stress that the categorical symmetry encoded by the bulk $G$-gauge theory not only contains the $G$ symmetry at the boundary, it also contains a dual algebraic higher symmetry $\tilde{G}^{(n-1)}$ at the boundary.

Did anything further come out of the ideas at holographic principle of higher category theory?
