Cosmological String Backgrounds
Abstract
Talk given at the ``4th Hellenic School on Elementary Particle Physics", Corfu, 220 September 1992: The propagation of strings in cosmological spacetime backgrounds is reviewed. We show the relation of a special class of cosmological backgrounds to exact conformal field theory. Particular emphasis is put on the singularity structure of the cosmological spacetime and on the discrete duality symmetries of the string background.
