Abstract: Abstract We describe a new procedure to obtain consistent backgrounds that uplift vacua and deformations of various maximal gauged supergravities by taking a known solution and performing singular limits along the moduli space of the… read more here.

Abstract: Abstract We present a new class of dualities relating non-geometric Calabi-Yau com- pactifications of type II string theory to T-fold compactifications of the heterotic string, both preserving four-dimensional $$ \mathcal{N} $$ N = 2 supersymmetry.… read more here.

DOI: 10.1016/j.physrep.2018.12.002
Abstract: Abstract This review provides an introduction to non-geometric backgrounds in string theory. Starting from a discussion of T-duality, geometric and non-geometric torus-fibrations are reviewed, generalised geometry and its relation to non-geometric backgrounds are explained and… read more here.
