Double field theory (DFT) is a proposal to incorporate T-duality, a distinctive symmetry of
string theory, as a symmetry of a field theory defined on a double configuration space. The …

We review recent developments in duality symmetric string theory. We begin with the world-
sheet doubled formalism which describes strings in an extended spacetime with extra …

We introduce the exceptional field theory for the group E 7 (7), based on a (4+ 56)-
dimensional spacetime subject to a covariant section condition. The “internal” generalized …

We present the details of the recently constructed E 6 (6)-covariant extension of 11-
dimensional supergravity. This theory requires a 5+ 27-dimensional spacetime in which the …

A bstract We consider a flux formulation of Double Field Theory in which fluxes are
dynamical and field-dependent. Gauge consistency imposes a set of quadratic constraints …

We show that generalised geometry gives a unified description of maximally supersymmetric
consistent truncations of ten‐and eleven‐dimensional supergravity. In all cases the …

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 …

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 …

We use exceptional field theory as a tool to work out the full nonlinear reduction ansatz for
the AdS 5× S 5 compactification of IIB supergravity and its noncompact counterparts in which …

A bstract We give the supersymmetric extension of exceptional field theory for E 7 (7), which
is based on a (4+ 56)-dimensional generalized spacetime subject to a covariant constraint …
