He also made significant contributions to mathematical physics, differential geometry, and group theory. He was widely regarded as one of the greatest mathematicians of the twentieth century. His works were collected from papers after his death by "Le Comite de publication des Oeuvers d"elie Cartan" and published by Centre National de la Recherche Scientifique, Paris.
