Informal Pizza SeminarMinimal Simple de Sitter SolutionsShajid HaqueUniversity of Wisconsin-MadisonI want to talk about the recent construction (arXiv:0810.5328) of explicit 4d de sitter solutions from Type IIA String theory pertubatively with a minimal set of ingredients - namely the O6-planes, non-zero Roman mass parameter, form fluxes and negative internal curvature. As an illustration for this type of construction, orientifolded compact hyperbolic spaces are considered and moduli are stabilized to a sufficiently weakly coupled and large volume regime.
