   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 at the high-energy boundary is related to a gauge theory of group in the low-energy bulk. In this paper, we stress that the categorical symmetry encoded by the bulk -gauge theory not only contains the symmetry at the boundary, it also contains a dual algebraic higher symmetry at the boundary.
