Gauged supergravities and non-geometric Q/R-fluxes from asymmetric orbifold CFT's
TL;DR: In this article, a general procedure for deriving the gauge algebra of the effective gauged supergravity using the exact CFT description at the orbifold point is given. But the results are restricted to the case of symmetric and asymmetric Z4xZ2 orbifolds.
Kasner solutions, climbing scalars and big-bang singularity
Cezar Condeescu,Emilian Dudas +1 more
TL;DR: In this paper, a scalar field close to big-bang is forced to climb a steep potential by its dynamics, and the conditions for climbing are formulated in the case of several scalars and after inclusion of higher-derivative corrections.

Asymmetric Orbifolds, Non-Geometric Fluxes and Non-Commutativity in Closed String Theory
TL;DR: In this article, the authors considered a class of exactly solvable closed string flux backgrounds that exhibit non-commutativity in the closed string coordinates, which are realized in terms of freely-acting asymmetric Z_N-orbifolds, and they explicitly constructed the modular invariant partition function of the models and derived the noncommutative algebra in the string coordinates.

Holomorphic variables in magnetized brane models with continuous Wilson lines
TL;DR: In this paper, the authors analyzed the action of the target-space modular group in toroidal type IIB orientifold compactifications with magnetized D-branes and continuous Wilson lines.
M-theory compactifications to three dimensions with M2-brane potentials
TL;DR: In this paper, a class of compactifications of M-theory to three dimensions that preserve N = 2 supersymmetry was studied, and the defining feature that a probe space-time filling M2 brane feels a non-trivial potential on the internal manifold.
