Henri Poincaré was one of the greatest mathematicians of the late nineteenth and early twentieth century. He revolutionized the field of topology, which studies. down into one or more of eight types of spaces, each with a certain homogeneous geometry. This became known as the geometrisation conjecture and implies the Poincaré.

Abstract: We discuss some of the key ideas of Perelman's proof of Poincaré's conjecture via the Hamilton program of using the Ricci flow, from the perspective of the modern theory of nonlinear partial differential equations En s'intéressant à la forme des objets, le grand mathématicien Henri Poincaré n'a pas manqué de se poser la question de la forme de l'Univers. Ainsi proposa-t-il un problème mathématique.
Email this Article Email Address: Poincaré conjecture Posed in 1904 by Henri Poincaré, the leading mathematician of his era and among the most gifted of all time, the Poincaré conjecture is a bold guess about nothing.
This conjecture was first proposed in 1904 by H. Poincaré (Poincaré 1953, pp. 486 and 498), and subsequently generalized to the conjecture that every compact n-manifold is homotopy-equivalent to the n-sphere iff it is homeomorphic to the n-sphere. The generalized statement reduces to the original conjecture for n==3 The Poincare Conjecture: Its Past, Present, and Future There has been a great deal of research surrounding the Poincare Conjecture since I first wrote this page many. The Poincaré conjecture, proposed by French mathematician Henri Poincaré in 1904, was one of key problems in topology. Any loop on a 3-sphere —as exemplified by the set of points at a distance of 1 from the origin in four-dimensional Euclidean space—can be contracted into a point The Poincaré Conjecture John W.
