Description
Various extensions of Poisson-Lie T-duality have been studied recently. For the duality group O(D,D), the most general extension is known as the generalized T-duality of generalized cosets (extending dressing cosets). In this talk, considering the U-duality group E_{n(n)}, I will explain a construction of the generalized cosets in exceptional geometry, which we call exceptional generalized cosets. I will then discuss the generalized U-dualities among different exceptional generalized cosets. I will also explain how the exceptional generalized cosets can be used to study consistent truncations of maximal supergravities. This talk is based on works with Falk Hassler, arXiv:2311.12095 and ongoing work.
