Abstract: Introduced by D. V. Anosov as the discrete time analogue of geodesic flows on Riemann manifolds of negative sectional curvature, Anosov diffeomorphisms constitute one of the leitmotivs of contemporary abstract dynamics. It is conjectured that these diffeomorphisms occur on very exceptional homogeneous spaces. The speaker will delineate the basic facts and briefly mention his own recent work towards settling this conjecture.
