Description

In this talk, I will give an introduction to `decomposition,' a property of d-dimensional QFTs with global (d-1)-form symmetries.
Decomposition is the observation that such quantum field theories are equivalent to disjoint unions of other quantum field theories, first observed in 2006 and studied in numerous examples and applications since.
I will outline some basic examples in two and four dimensions, and as time
permits, discuss various applications.
