Since it was proposed by polymath H. Poincare' in 1904, who sought to mathematically define the topology of a sphere, mathematicians had sought to prove the theorem. For more than a century, the best ...

Hyam Rubinstein receives funding from the Australian Research Council and has also received funding from several mining companies for research on the optimal design of access networks in underground ...

MADRID, Spain – The Poincare conjecture involves topology, a branch of math that studies shapes. It essentially says that in three dimensions you cannot transform a doughnut shape into a sphere ...

Le Russe Grigori Perelman a été de nouveau récompensé jeudi par le Clay Mathematics Institute pour avoir résolu la conjecture de Poincaré, listée par cet institut comme l'un des sept problèmes les ...

World top mathematician Richard Hamilton has recognized the work of Chinese mathematicians on giving a complete proof of the century-old puzzle of Poincare Conjecture. Foreign member of the Chinese ...

Si la conjecture a induit une longue liste de preuves incorrectes, certaines d'entre elles ont toutefois mené à une meilleure compréhension de la topologie en petites dimensions.

In early April 2002, Dr. Grigori Perelman of the Steklov Institute of Mathematics in St. Petersburg gave a series of public lectures at the Massachusetts Institute of Technology. In the lectures he ...
