Description
In this talk I will discuss the interplay between supersymmetry and two-dimensional de Sitter space. In particular we consider a gauge fixed form of 2d supergravity coupled to an N=2 superconformal field theory. The resulting theory is known as N= 2 Liouville theory and also makes an appearance as the non-critical superstring theory. N=2 super Liouville admits a positive cosmological constant and is possibly a UV complete theory. I will discuss and contrast the results of supersymmetric localization and the explicit higher-loop evaluation of the gravitational path integral around its two-dimensional saddle.
