One-point functions for $C_{2}$ -cofinite VOAs: pseudo-traces and trace spaces of projective modules

Max-Niklas Steffen

We study the space of one-point functions on the torus for a possibly nonrational $C_{2}$ -cofinite vertex operator algebra $V$ by relating it to a trace object of the subcategory of…

A Boundary Characterization of Turaev-Viro TQFTs

Max-Niklas Steffen, Christoph Schweigert

We consider three-dimensional topological field theories on manifolds with boundary defects and identify explicit boundary locality conditions. We show that these conditions imply…
