A bstractWe rewrite the recently derived cubic action of Double Field Theory on group manifolds [1] in terms of a generalized metric and extrapolate it to all orders in the fields. For the resulting action, we derive the field equations and state them in terms of a generalized curvature scalar and a generalized Ricci tensor. Compared to the generalized metric formulation of DFT derived from tori, all these quantities receive additional contributions related to the non-trivial background. It is… 

Flux formulation of DFT on group manifolds and generalized Scherk-Schwarz compactifications

A bstractA flux formulation of Double Field Theory on group manifold is derived and applied to study generalized Scherk-Schwarz compactifications, which give rise to a bosonic subsector of

The topology of Double Field Theory

A bstractWe 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 discussion and so G

We revisit the generalized connection of Double Field Theory. We implement a procedure that allow us to re‐write the Double Field Theory equations of motion in terms of geometric quantities (like

Metric Algebroid and Poisson-Lie T-duality in DFT

In this article we investigate the gauge invariance and duality properties of DFT based on a metric algebroid formulation given previously in [1]. The derivation of the general action given in this

Relating double field theory to the scalar potential of N = 2 gauged supergravity

A bstractThe double field theory action in the flux formulation is dimensionally reduced on a Calabi-Yau three-fold equipped with non-vanishing type IIB geometric and non-geometric fluxes. First, we

Perturbative double field theory on general backgrounds

We develop the perturbation theory of double field theory around arbitrary solutions of its field equations. The exact gauge transformations are written in a manifestly background covariant way and

A geometric formulation of exceptional field theory

A bstractWe formulate the full bosonic SL(5) exceptional field theory in a coordinateinvariant manner. Thereby we interpret the 10-dimensional extended space as a manifold with SL(5) × ℝ+-structure.

Properties of double field theory

In this thesis we study several aspects of Double Field Theory (DFT). In general, Double Field Theory is subject to the so-called strong constraint. By using the Flux Formulation of DFT, we explore

The spacetime of double field theory: Review, remarks, and outlook

Extended geometry and gauged maximal supergravity

A bstractWe consider generalized diffeomorphisms on an extended mega-space associated to the U-duality group of gauged maximal supergravity in four dimensions, E7(7). Through the bein for the

The geometry behind double geometry

A bstractGeneralised diffeomorphisms in double field theory rely on an O(d, d) structure defined on tangent space. We show that any (pseudo-)Riemannian metric on the doubled space defines such a

Consistent compactification of double field theory on non-geometric flux backgrounds

A bstractIn this paper, we construct non-trivial solutions to the 2D-dimensional field equations of Double Field Theory (DFT) by using a consistent Scherk-Schwarz ansatz. The ansatz identifies 2(D −

Star products on graded manifolds and α′-corrections to Courant algebroids from string theory

Courant algebroids, originally used to study integrability conditions for Dirac structures, have turned out to be of central importance to study the effective supergravity limit of string theory. The

Generalized metric formulation of double field theory

The generalized metric is a T-duality covariant symmetric matrix constructed from the metric and two-form gauge field and arises in generalized geometry. We view it here as a metric on the doubled
