Abstract：In this talk, we revisit the problem of boundary excitations at a topological boundary or junction defects between topological boundaries in non-chiral bosonic topological orders in 2+1 dimensions. Based on physical considerations, we derive a formula that relates the fusion rules of the boundary excitations, and the “half-linking” number between condensed anyons and confined boundary excitations. This formula is a direct analogue of the Verlinde formula.
