All maximal gauged supergravities with uplift
Falk Hassler, Yuho Sakatani
Generalised parallelisable spaces permit to uplift many maximal gauged supergravities to ten or eleven dimensions. While some of the former are explicitly known, the literature is…
Discrete Anomaly Matching for the Pouliot Type Dualities
Teruhiko Kawano
We compute the 't Hooft anomalies of discrete symmetries in the Pouliot type dual theories and check their anomaly matching conditions. The Pouliot type dual theories we will consi…
Poisson-Lie T-plurality for dressing cosets
Yuho Sakatani
The Poisson-Lie T-plurality is an equivalence of string theories on various cosets , , , where is a Drinfel'd d…
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…
E Exceptional Drinfel'd Algebras
Emanuel Malek, Yuho Sakatani, Daniel C. Thompson
The exceptional Drinfel'd algebra (EDA) is a Leibniz algebra introduced to provide an algebraic underpinning with which to explore generalised notions of U-duality in M-theory. In…
Born sigma model for branes in exceptional geometry
Yuho Sakatani, Shozo Uehara
In double field theory, the physical space has been understood as a subspace of the doubled space. Recently, the doubled space is defined as the para-Hermitian manifold and the phy…
Non-Abelian U-duality for membrane
Yuho Sakatani, Shozo Uehara
T-duality of string theory can be extended to the Poisson-Lie T-duality when the target space has a generalized isometry group given by a Drinfel'd double. In M-theory, T-duality i…
U-duality extension of Drinfel'd double
Yuho Sakatani
A family of algebras that extends the Lie algebra of the Drinfel'd double is proposed. This allows us to systematically construct the generalized frame fields $E_A{…
Duality rules for more mixed-symmetry potentials
Yuho Sakatani
T- and S-duality rules among the gauge potentials in type II supergravities are studied. In particular, by following the approach of arXiv:1909.01335, we determine the T- and S-dua…
Exotic branes and mixed-symmetry potentials II: Duality rules and exceptional -form gauge fields
Jose J. Fernandez-Melgarejo, Yuho Sakatani, Shozo Uehara
In U-duality-manifest formulations, supergravity fields are packaged into covariant objects such as the generalized metric and -form fields . While a parame…
Exotic branes and mixed-symmetry potentials I: predictions from symmetry
Jose J. Fernandez-Melgarejo, Yuho Sakatani, Shozo Uehara
Type II string theory or M-theory contains a broad spectrum of gauge potentials. In addition to the standard -form potentials, various mixed-symmetry potentials have been predic…
Type II DFT solutions from Poisson-Lie T-duality/plurality
Yuho Sakatani
String theory has the T-duality symmetry when the target space has Abelian isometries. A generalization of the T-duality, where the isometry group is non-Abelian, is known as the n…
Weyl invariance of string theories in generalized supergravity backgrounds
Jose J. Fernandez-Melgarejo, Jun-ichi Sakamoto, Yuho Sakatani +1
We revisit Weyl invariance of string theories in generalized supergravity backgrounds. In the previous work arXiv:1703.09213, a possible counterterm was constructed, but it seems t…
Holographic integration of and via
Thiago Araujo, Eoin Ó Colgáin, Yuho Sakatani +2
Prompted by the recent developments in integrable single trace and deformations of 2d CFTs, we analyse such deformations in the context of fro…
Weaving the Exotic Web
Jose J. Fernandez-Melgarejo, Tetsuji Kimura, Yuho Sakatani
String and M-theory contain a family of branes forming U-duality multiplets. In particular, standard branes with codimension higher than or equal to two, can be explicitly found as…
Local -deformations and Yang-Baxter sigma model
Jun-ichi Sakamoto, Yuho Sakatani
Homogeneous Yang-Baxter (YB) deformation of AdSS superstring is revisited. We calculate the YB sigma model action up to quadratic order in fermions and show that homo…
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…
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…

Kanghoon Lee, Soo-Jong Rey, Yuho Sakatani
The (heterotic) double field theories and the exceptional field theories are recently developed for manifestly duality covariant formulation of various supergravity theories, descr…
