Abstract :
After reviewing flux compactifications of type IIA supergravity on CY3 and
more general SU(3)-structure manifolds, I will discuss the prospect of
obtaining dS vacua and slow-roll inflation from the resulting scalar
potentials. Then I talk about compactifications on six dimensional manifolds
with SU(2)-structure group, that are related by one T-duality to certain
SU(3)-structure spaces with potentially "non-geometric" fluxes. I show that
they allow for a complete moduli stabilization in type IIB already at
tree-level and comment on the possibility of finding dS vacua and slow-roll
inflation in such SU(2)-structure compactifications.
