How hard is it to get a de Sitter solution in String Theory?

Keshav Dasgupta
McGill

Abstract:

In this talk I will argue that a de Sitter solution in string theory is hard to get, although not impossible. I'll show a possible way to realize KKLT type solution using string theory fluxes and discuss the status of other possible ways to achieve de Sitter vacua.
