Invariants of r-spin TQFTs and non-semisimplicity

Nils Carqueville, Ehud Meir, Lorant Szegedy

For a positive integer r, an r-spin topological quantum field theory is a 2-dimensional TQFT with tangential structure given by the r-fold cover of SO_2 . In particular, such a TQF…

Parity and Spin CFT with boundaries and defects

Ingo Runkel, Lóránt Szegedy, Gérard M. T. Watts

This paper is a follow-up to [arXiv:2001.05055] in which two-dimensional conformal field theories in the presence of spin structures are studied. In the present paper we define fou…

Fully extended -spin TQFTs

Nils Carqueville, Lóránt Szegedy

We prove the -spin cobordism hypothesis in the setting of (weak) 2-categories for every positive integer : The 2-groupoid of 2-dimensional fully extended -spin TQFTs with…

Topological field theories on open-closed -spin surfaces

Walker H. Stern, Lóránt Szegedy

In this article, we establish a connection between two models for -spin structures on surfaces: the marked PLCW decompositions of Novak and Runkel-Szegedy, and the structured gr…

On invertible 2-dimensional framed and -spin topological field theories

Lóránt Szegedy

We classify invertible 2-dimensional framed and -spin topological field theories by computing the homotopy groups and the -invariant of the corresponding bordism categories.…

Symmetry defects and orbifolds of two-dimensional Yang-Mills theory

Lukas Müller, Richard J. Szabo, Lóránt Szegedy

We describe discrete symmetries of two-dimensional Yang-Mills theory with gauge group associated to outer automorphisms of , and their corresponding defects. We show that th…
