Quantized topological terms in weak-coupling gauge theories with a global symmetry and their connection to symmetry-enriched topological phases

We study the quantized topological terms in a weak-coupling gauge theory with gauge group G[subscript g] and a global symmetry G[subscript s] in d space-time dimensions. We show that the quantized topological terms are classified by a pair (G,ν[subscript d]), where G is an extension of G[subscript s...
