Titre: The early times of stationary cosmologies

Abstract: The Steady-state model of Bondi and Gold, on the one hand, and Hoyle’s model on the other hand are the most famous examples of stationary cosmologies. However, they are actually quite different in terms of motivations and content and were not the only stationary models. In this talk, we will look back at the very beginning of relativistic cosmology and the first stationary cosmological models. They were lead by various motivations and suggest a surprising phenomenon: creation of matter. From Einstein to Hoyle, we will follow the different stationary cosmologies, their development and their interplay.
