Duality as a symmetry principle for sigma models
Sigma models are a big class of theories, omnipresent in many branches of physics -- from condensed matter over particle physics to gravity and string theory. In this talk I want to motivate how a mathematical tool from string theory, duality and so-called generalized geometry, can be used to approach and get new insights into general sigma models. In particular, I will emphasize the role that generalized geometry plays for topological sigma models, integrable sigma models and those with non-commutative field spaces.
