Résumé |
Our universe is currently observed to be in accelerated expansion, as it probably
was in its early days during
an inflation phase. Reproducing this phenomenon from string theory, providing this
way an origin to dark
energy, has proven to be very challenging. We will discuss the progress and
difficulties in doing so, either by
finding classical de Sitter solutions, or by obtaining scalar potentials with
appropriate slopes.
Time allowing, we will present side results related to string theory scalar
potentials, namely the Massless
Minkowski Conjecture, and a mass bound for (susy) anti-de Sitter solutions. |
