Integrable 2d sigma models and renormalisation group flow

Starts at:Mon 28 Oct 2019, 14:00
Speaker:Ben HoareInstitute:

Abstract:Many classically integrable sigma-models are known to be solutions of the 1-loop renormalisation group equations, or "Ricci flow". In this talk we will investigate what happens at higher loops and explore the quantum corrections required to preserve renormalisability. Applying this analysis to deformed duals of integrable sigma-models, we will argue that non-abelian duality commutes with renormalisation group flow.
