Extended Riemannian Geometry III: Global Double Field Theory with Nilmanifolds
Andreas Deser, Christian Saemann
We describe the global geometry, symmetries and tensors for Double Field Theory over pairs of nilmanifolds with fluxes or gerbes. This is achieved by a rather straightforward appli…
Global Seiberg-Witten maps for U(n)-bundles on tori and T-duality
Paolo Aschieri, Andreas Deser
Seiberg-Witten maps are a well-established method to locally construct noncommutative gauge theories starting from commutative gauge theories. We revisit and classify the ambiguiti…
Derived Brackets and Symmetries in Generalized Geometry and Double Field Theory
Andreas Deser, Christian Saemann
Derived brackets as introduced and studied by Kosmann-Schwarzbach and Voronov are a powerful tool for describing and understanding infinitesimal symmetry actions relevant in physic…
Gauging as constraining: the universal generalised geometry action in two dimensions
Athanasios Chatzistavrakidis, Andreas Deser, Larisa Jonke +1
One of the central concepts in modern theoretical physics, gauge symmetry, is typically realised by lifting a finite-dimensional global symmetry group of a given functional to an i…
Non-geometric strings, symplectic gravity and differential geometry of Lie algebroids
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Based on the structure of a Lie algebroid for non-geometric fluxes in string theory, a differential-geometry calculus is developed which combines usual diffeomorphisms with so-call…
A bi-invariant Einstein-Hilbert action for the non-geometric string
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Inspired by recent studies on string theory with non-geometric fluxes, we develop a differential geometry calculus combining usual diffeomorphisms with what we call beta-diffeomorp…
