Towards All Categorical Symmetries in 2+1 Dimensions
Mathew Bullimore, Jamie J. Pearson
We investigate the most general gauging operations in 2+1 dimensional oriented field theories with finite symmetry groups, which correspond to gapped boundary conditions in 3+1 dim…
Representation theory for categorical symmetries
Thomas Bartsch, Mathew Bullimore, Andrea Grigoletto
This paper addresses the question of how categorical symmetries act on extended operators in quantum field theory. Building on recent results in two dimensions, we introduce higher…
Higher representations for extended operators
Thomas Bartsch, Mathew Bullimore, Andrea Grigoletto
It is known that local operators in quantum field theory transform in representations of ordinary global symmetry groups. The purpose of this paper is to generalise this statement…
Generalized Symmetries and Anomalies of 3d N=4 SCFTs
Lakshya Bhardwaj, Mathew Bullimore, Andrea E. V. Ferrari +1
We study generalized global symmetries and their 't Hooft anomalies in 3d N=4 superconformal field theories (SCFTs). Following some general considerations, we focus on good quiver…
Non-invertible Symmetries and Higher Representation Theory II
Thomas Bartsch, Mathew Bullimore, Andrea E. V. Ferrari +1
In this paper we continue our investigation of the global categorical symmetries that arise when gauging finite higher groups and their higher subgroups with discrete torsion. The…
Non-invertible Symmetries and Higher Representation Theory I
Thomas Bartsch, Mathew Bullimore, Andrea E. V. Ferrari +1
The purpose of this paper is to investigate the global categorical symmetries that arise when gauging finite higher groups in three or more dimensions. The motivation is to provide…
