Description
I will talk about a construction of topological lines in 1+1d holomorphic CFT in terms of symmetry TFT. In particular, the method is applied to a construction of topological lines in the chiral free fermion theory that intertwines the global symmetry currents nontrivially. Upon folding, this construction in turn provides a boundary condition in the non-chiral fermion theory that preserves a not-vector-like anomaly-free symmetry, which is in relation to monopole scattering problem. Based on an on-going work with Masataka Watanabe.
