Refined half-integer condition on RG flows
Ken Kikuchi
Renormalization group flows are constrained by symmetries. Traditionally, we have made the most of 't Hooft anomalies associated to the symmetries. The anomaly is mathematically pa…

Rational RG flow, extension, and Witt class
Ken Kikuchi
Consider a renormalization group flow preserving a pre-modular fusion category . If it flows to a rational conformal field theory, the surviving symmetry $\mathcal S_…
