Abstract: I motivate my talk with three questions in (1+1)d CFT: (1) What is the interpretation of correlators in neither Euclidean nor Lorentzian regime? (2) Is there a connection between Lorentzian dynamics and line operators? (3) Can the Verlinde algebra be made sense of in irrational theories? I will argue that the answer to (3) is "yes", and via (2) this "algebra" can put nontrivial unitarity bounds ("opacity bound") on the conformal Regge limit of four-point functions. Topological defect lines play a key role in this story. More details can be found in my paper 2012.01429.
