Abstract：In this talk, we show how to generalize the electric-magnetic (EM) duality in the quantum double (QD) models to the extended QD models of topological orders with gapped boundaries. We also show that an extended QD model can be mapped to an extended Levin-Wen (LW) model with gapped boundaries via Fourier transform and rewriting local basis. The transformed extended QD model elucidates the phenomenon of anyon splitting in anyon condensation.
