On de Sitter Vacua in Type IIA Orientifold Compactifications
Frank Saueressig, Ulrich Theis, Stefan Vandoren
This letter discusses the orientifold projection of the quantum corrections to type IIA strings compactified on rigid Calabi-Yau threefolds. It is shown that N=2 membrane instanton…
Membrane Instantons and de Sitter Vacua
Marijn Davidse, Frank Saueressig, Ulrich Theis +1
We investigate membrane instanton effects in type IIA strings compactified on rigid Calabi-Yau manifolds. These effects contribute to the low-energy effective action of the univers…
Singular compactifications and cosmology
Laur Jarv, Thomas Mohaupt, Frank Saueressig
We summarize our recent results of studying five-dimensional Kasner cosmologies in a time-dependent Calabi-Yau compactification of M-theory undergoing a topological flop transition…
