Title: 
Search for meta-stable dS-vacua in IIA/CY strings
Abstract: 

In the 1st part of my talk I introduce general motivation for superstring cosmology needed to describe dark energy and UV completion of (large field) inflationary models. In the 2nd part I describe our calculations of scalar potentials in the gauged 4D, N=2 supergravities arising from (consistent) flux compactifications of type IIA strings on rigid CY three-folds. Our models are based on the universal hypermultiplet with some number of (abelian) N=2 vector multiplets. They allow
us to have full control over all quantum corrections that are governed by an integrable system. I give some explicit examples of moduli stabilisation and exact low-energy effective actions.
