The aim of the school is to provide a thorough description of the interactions between geometry (with its different branches) and dynamical systems, in one part, and between these two disciplines and different extra-mathematics areas of research (General Relativity, Cosmology, Black Holes, ……), in other part. A pedagogical treatment of the subjects, at both the introductory and advanced level, will be provided in the form of a series of lectures by individual speakers, ranging from evolutions of the subject till the most recent developments.
