Focus week on string cosmology, Oct 4-8, 2010

Focus week on string cosmology

We project a workshop on string cosmology just after the COSMO/CosPa 2010 conference.

Covered topics include stringy inflation models, string phenomenology, and various theoretical approaches to string cosmology.

The daily schedule will include a few presentations and plenty of time for informal discussions.
