SUSY Breaking, Cosmology, Vacuum Selection and the Cosmological Constant in String Theory

Abstract

This is the written version of a talk given at the Santa Barbara Workshop on Supersymmetry in December of 1995. It summarizes a collection of results on superstring cosmology obtained by the author and various collaborators, and contains some speculations about the resolution of the cosmological constant and vacuum selection problems in string theory.
