The Hierarchy of Curvatures in Exceptional Geometry
Falk Hassler, Yuho Sakatani
Despite remarkable success in describing supergravity reductions and backgrounds, generalized geometry and the closely related exceptional field theory are still lacking a fundamen…
Gauged sigma models and exceptional dressing cosets
Yuho Sakatani, Shozo Uehara
The Poisson-Lie (PL) T-duality is a generalized T-duality based on the Lie algebra of the Drinfel'd double. In particular, when we consider the PL T-duality of a coset space, the d…
Half-maximal Extended Drinfel'd Algebras
Yuho Sakatani
Extended Drinfel'd algebra (ExDA) is the underlying symmetry of non-Abelian duality in the low-energy effective theory of string theory. Non-Abelian U-dualities in maximal supergra…
Jacobi-Lie T-plurality
Jose J. Fernandez-Melgarejo, Yuho Sakatani
We propose a Leibniz algebra, to be called DD, which is a generalization of the Drinfel'd double. We find that there is a one-to-one correspondence between a DD and a Jacob…
Poisson-Lie T-plurality for WZW backgrounds
Yuho Sakatani
Poisson-Lie T-plurality constructs a chain of supergravity solutions from a Poisson-Lie symmetric solution. We study the Poisson-Lie T-plurality for supergravity solutions with …
Extended Drinfel'd algebras and non-Abelian duality
Yuho Sakatani
A Drinfel'd algebra gives the systematic construction of generalized parallelizable spaces and this allows us to study an extended T-duality, known as the Poisson-Lie T-duality. Re…
