Especially he discovered so called Poincare duality that says " the Betti numbers equidistant from the ends are equal". This fundamental property of closed manifolds has very large generalization up to homotopy invariants of non simply connected manifolds. In my lecture I shall describe the methods of so called noncommutative geometry and toplogy to different contemporary problems of differential topology. |
