EXOTIC SYMMETRIES : NEW VIEWS ABOUT SPACE

Pierre Cartier
(Institut des Hautes Etudes Scientifiques)
Abstract
The recent developments of Mathematical Physics have brought very new ideas about the nature of space . I will argue that we have to mix the methods of noncommutative geometry of Alain Connes with the prophetic views of Grothendieck about the so-called motives and their motivic Galois group .
The dream of a "cosmic Galois group" may soon become an established reality .
