On U-Folds and Their Construction
Stefano Maurelli, Ruggero Noris, Marcelo Oyarzo +1
We review a general paradigm for constructing U-fold backgrounds in (dimensionally reduced) Type IIB superstring theory, of the form , with a m…

The Instability of Low-Temperature Black Holes in Gauged Supergravity
Andrés Anabalón, Stefano Maurelli, Marcelo Oyarzo +1
We consider the static planar black hole solutions in the STU model of the gauged supergravity in four dimensions. We give a straightforward derivation of the equat…
