0-form, 1-form, and 2-group symmetries via cutting and gluing of orbifolds
0-form, 1-form, and 2-group symmetries via cutting and gluing of orbifolds
Orbifold singularities of M-theory constitute the building blocks of a broad class of supersymmetric quantum field theories (SQFTs). In this paper we show how the local data of these geometries determines global data on the resulting higher symmetries of these systems. In particular, via a process of cutting and gluing, …
