Abstract

Topological defect lines in 2D generalize both global symmetries and Verlinde lines, and provide models of fusion categories without braiding. I will discuss their roles in CFTs and in constraining RG flows, and use them to determine the infrared (fully extended) topological quantum field theory in some examples of massive flows.
