Bicategories for TQFTs with Defects with Structure
I. J. Lee, D. N. Yetter
We provide a description of adequate categorical data to give a Turaev-Viro type state-sum construct of invariants of 3-manifolds with a system of defects, generalizing the Dijkgra…

Dijkgraaf-Witten Type Invariants of Seifert Surfaces in 3-Manifolds
I. J. Lee, D. N. Yetter
We introduce defects, with internal gauge symmetries, on a knot and Seifert surface to a knot into the combinatorial construction of finite gauge-group Dijkgraaf-Witten theory. The…
