Abstract
In recent years, our understanding of the generalized symmetries has been greatly evolved in terms of topological defect surfaces in QFTs. In this talk, I will focus on the generalized symmetries in 2d CFTs and the symTFTs associated with them. I will explain that gauging different generalized symmetries in a 2d CFT are one-to-one correspondence to various Lagrangian algebras in the symTFTs. Further applying these data, one can construct topological interfaces connecting the original theory and the orbifolded one. Finally, I will show how to use these interfaces to map boundary states in different orbifold phases.
