This is a review of exceptional field theory: a generalisation of Kaluza–Klein theory that
unifies the metric and p-form gauge field degrees of freedom of supergravity into a …

A bstract The α′-deformed frame-like Double Field Theory (DFT) is a T-duality and gauge
invariant extension of DFT in which generalized Green-Schwarz transformations provide a …

Abstract Taking O (D, D) O (D, D) covariant field variables as its truly fundamental
constituents, Double Field Theory can accommodate not only conventional supergravity but …

A bstract We describe the doubled space of Double Field Theory as a group manifold G with
an arbitrary generalized metric. Local information from the latter is not relevant to our …

A bstract 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 …

The metric algebroid proposed by Vaisman (the Vaisman algebroid) governs the gauge
symmetry algebra generated by the C-bracket in double field theory (DFT). We show that the …

A bstract We construct ad= 11 supergravity analogue of the open-closed string map in the
context of SL (5) Exceptional Field Theory (ExFT). The deformation parameter tri-vector Ω …

A bstract In recent years, it has been widely argued that the duality transformations of string
and M-theory naturally imply the existence of so-called 'exotic branes'—low codimension …

In this work, we generalise the procedure of the non-abelian T-duality based on a B-shift and
a sequence of formal abelian T-dualities in non-isometric directions to 11-dimensional …

Abstract Kaluza‐Klein Theory states that a metric on the total space of a principal bundle, if it
is invariant under the principal action of P, naturally reduces to a metric together with a …
