Extended Riemannian Geometry I: Local Double Field Theory
Andreas Deser, Christian Saemann
We present an extended version of Riemannian geometry suitable for the description of current formulations of double field theory (DFT). This framework is based on graded manifolds…
Strings in Singular Space-Times and their Universal Gauge Theory
Athanasios Chatzistavrakidis, Andreas Deser, Larisa Jonke +1
We study the propagation of bosonic strings in singular target space-times. For describing this, we assume this target space to be the quotient of a smooth manifold by a singul…
Beyond the standard gauging: gauge symmetries of Dirac Sigma Models
Athanasios Chatzistavrakidis, Andreas Deser, Larisa Jonke +1
In this paper we study the general conditions that have to be met for a gauged extension of a two-dimensional bosonic sigma-model to exist. In an inversion of the usual approach of…
