Exceptional M-brane sigma models and -symbols
Yuho Sakatani, Shozo Uehara
We develop the M-brane actions proposed in arXiv:1607.04265 by using -symbols determined in arXiv:1708.06342. Introducing -forms that are defined with the -symbols, we pre…
-folds from Yang-Baxter deformations
Jose J. Fernandez-Melgarejo, Jun-ichi Sakamoto, Yuho Sakatani +1
Yang-Baxter (YB) deformations of type IIB string theory have been well studied from the viewpoint of classical integrability. Most of the works, however, are focused upon the local…
-symbols in exceptional field theory
Yuho Sakatani, Shozo Uehara
We present the universal form of -symbols that can be applied to an arbitrary exceptional field theory (EFT) up to . We then express the -tensor, which govern…
Homogeneous Yang-Baxter deformations as generalized diffeomorphisms
Jun-ichi Sakamoto, Yuho Sakatani, Kentaroh Yoshida
Yang-Baxter (YB) deformations of string sigma model provide deformed target spaces. We propose that homogeneous YB deformations always lead to a certain class of -twisted backgr…
Weyl invariance for generalized supergravity backgrounds from the doubled formalism
Jun-ichi Sakamoto, Yuho Sakatani, Kentaroh Yoshida
It has recently been shown that a set of the generalized type IIB supergravity equations follows from the requirement of kappa symmetry of the type IIB Green-Schwarz superstring th…
Connecting M-theory and type IIB parameterizations in Exceptional Field Theory
Yuho Sakatani, Shozo Uehara
In the exceptional field theory, there are two natural parameterizations for the generalized metric; in terms of bosonic fields in the eleven-dimensional supergravity (M-theory par…
