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…

Stratified spaces, Directed Algebraic Topology, and State-Sum TQFTs

I. J. Lee, D. N. Yetter

We apply the theory of directed topology developed by Grandis [9, 10] to the study of stratified spaces by describing several ways in which a stratification or a stratification wit…

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…
