B-twisted Gaiotto-Witten theory and topological quantum field theory

Niklas Garner, Nathan Geer, Matthew B. Young

We develop representation theoretic techniques to construct three dimensional non-semisimple topological quantum field theories which model homologically truncated topological B-tw…

Frobenius--Schur indicators for twisted Real representation theory and two dimensional unoriented topological field theory

Levi Gagnon-Ririe, Matthew B. Young

We construct a two dimensional unoriented open/closed topological field theory from a finite graded group $π : G^↠ {1, - 1}$ , a $π$ -twisted $2$ -cocycle $θ^$ …
