What have we learned and what can we learn from spatially homogenous cosmology?

Uggla, C (Karlstad)
Friday 16 September 2005, 11:30-12:30

Seminar Room 1, Newton Institute


During the last few decades there has been considerable progress as regards rigorous mathematical results about the dynamics of spatially homogeneous cosmological models. Rather than focusing on particular results the emphasis in this talk will be on the underlying reasons why any results at all have been found. It will be shown that the key reason is associated with a hierarchical structure that arises from space-time symmetry properties, scale transformations, and the state space features these induce.
