Topological terms of (2+1)d flag-manifold sigma models
Abstract We examine topological terms of (2 + 1)d sigma models and their consequences in the light of classifications of invertible quantum field theories utilizing bordism groups. In particular, we study the possible topological terms for the U(N)/U(1) N flag-manifold sigma model in detail. We argu...
