Description:
Author(s): Ling-Yan Hung and Xiao-Gang Wen We study the quantized topological terms in a weak-coupling gauge theory with gauge group G g and a global symmetry G s in d space-time dimensions. We show that the quantized topological terms are classified by a pair ( G , ν d ), where G is an extension of G s by G g and ν d an element in group cohomology H d ... [Phys. Rev.
