| Titre | Universal 1-loop beta functions for integrable sigma models |
| Résumé | I will present a simple, new method for the 1-loop renormalization of integrable sigma models, by treating equations of motion and Bianchi identities on an equal footing. The resulting beta functions take a universal form in terms of the Lax connection, generalizing case-by-case computations in the literature. We will discuss possible applications to (i) proving the renormalizability of integrable sigma-models and (ii) finding new supergravity solutions. |
