A bstract We present the generalized Scherk-Schwarz reduction ansatz for the full
supersymmetric exceptional field theory in terms of group valued twist matrices subject to …

A bstract We investigate α′ corrections of bosonic strings in the framework of double field
theory. The previously introduced “doubled α′-geometry” gives α′-deformed gauge …

A bstract A new version of double field theory (DFT) is derived for the exactly solvable
background of an in general left-right asymmetric WZW model in the large level limit. This …

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 …

The cobordism conjecture of the swampland program states that the bordism group of
quantum gravity must be trivial. We investigate this statement in several directions, on both …

A bstract In the first half of the paper, we study in details NS-branes, including the NS 5-
brane, the Kaluza-Klein monopole and the exotic\({5}^{\frac {2}{2}}\)-or Q-brane, together …

We explore several consequences of the recently discovered intrinsic noncommutativity of
the zero-mode sector of closed string theory. In particular, we illuminate the relation between …

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 …

We discuss the possible realisation in string/M theory of the recently discovered family of
four‐dimensional maximal gauged supergravities, and of an analogous family of seven …

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 …
