Résumé |
In this seminar, I will discuss integrable systems called affine Gaudin models and their application to the study
of integrable sigma models. As an introductory example, I will first discuss a simpler class of Gaudin models,
the finite ones, and their relation with integrable spin chains and mechanical systems. I will then explain how
to use affine Gaudin models to construct new integrable classical sigma models, by coupling together an
arbitrary number of principal chiral models with Wess-Zumino terms. |
