Jules Henri Poincaré (29 April 1854 – 17 July 1912) was a French mathematician and scientist. He was described as a "monster of mathematics " when still a child. Many people think he was the last person to understand all branches of ...

Dec 22, 2006 · The Poincaré Conjecture--Proved. To mathematicians, Grigori Perelman's proof of the Poincaré conjecture qualifies at least as the Breakthrough of the Decade. But it has taken them a good part of that decade to convince themselves that it was for real. In 2006, nearly 4 years after the Russian mathematician released the first of three papers ...

Poincaré Conjecture. If we stretch a rubber band around the surface of an apple, then we can shrink it down to a point by moving it slowly, without tearing it and without allowing it to leave the surface. On the other hand, if we imagine that the same rubber band has somehow been stretched in the appropriate direction around a doughnut, then ...

Feb 9, 2023 · Poincaré conjecture, in topology, conjecture—now proven to be a true theorem—that every simply connected, closed, three-dimensional manifold is topologically equivalent to S3, which is a generalization of the ordinary sphere to a higher dimension (in particular, the set of points in four-dimensional space that are equidistant from the origin). The conjecture was made in 1904 by the French ...
