    WITS node seminar: Dr. Shajid Haque (University of the Witwatersrand)

    Abstract: The talk will be about the search for accelerating power-law solutions in heterotic string theory with NS-NS fluxes compactified on half-flat and generalized half-flat manifolds. We restrict our searches to the STZ sector of the theory and include linear order alpha' corrections. We find two ekpyrotic solutions in the case when the heterotic string theory is compactified on generalized half-flat manifolds. We do not find accelerating solutions in any of the models.
