SUMMARY:Problems with de Sitter in string theory\, Theory Seminar (Hig
 h Energy/Cosmology)\, Daniel Junghans\, Institute for Theoretical Phys
 ics\, TU Wien
DESCRIPTION:The simplest explanation for the observed accelerating exp
 ansion of our universe is that we live in an approximate de Sitter spa
 ce. On the other hand\, there is growing evidence that various popular
  proposals for realizing de Sitter space in string theory do not self-
 consistently control neglected string corrections. In this talk\, we s
 how such a control problem in two rather different proposals: the larg
 e-volume scenario and the supercritical scenario.
