Description
A d-dimensional QFT with a (d-1)-form global symmetry decomposes into a disjoint union of different QFTs related by a (-1)-form symmetry. In this talk I will discuss these symmetries and the associated decomposition in the framework of the Symmetry TFT, using various examples such as 4d Yang—Mills or 3d ABJ(M) theories.
