BID - Quantum field theory with boundaries, impurities, and defects

We will discuss non-invertible 0-form symmetries of 3d TQF Ts and their gauging from the perspective of anyon condensation, topological domain walls, and separable algebras in fusion 2-categories, with examples in 2+1d Z_2 gauge theory.
