Has the Poincaré conjecture been proven?

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 …

Is the Poincaré conjecture solved?

As of October 17, 2021, the Poincaré conjecture is the only solved Millennium problem. On December 22, 2006, the journal Science honored Perelman’s proof of the Poincaré conjecture as the scientific “Breakthrough of the Year”, the first time this honor was bestowed in the area of mathematics.

Where is Perelman now?

Perelman lives with his mother in a spartan apartment in a St. Petersburg suburb.

What is Poincaré conjecture used for?

The Poincare Conjecture is essentially the first conjecture ever made in topology; it asserts that a 3-dimensional manifold is the same as the 3-dimensional sphere precisely when a certain algebraic condition is satisfied. The conjecture was formulated by Poincare around the turn of the 20th century.

Who solved the Poincare?

Grigori “Grisha” Perelman
Russian mathematician Grigori “Grisha” Perelman was awarded the Prize on March 18 last year for solving one of the problems, the Poincaré conjecture – as yet the only one that’s been solved. Famously, he turned down the $1,000,000 Millennium Prize.

Is Perelman genius?

Considered one of the world’s smartest men, Perelman published two proofs of the theorem in 2002 and 2003. It took until last year for a team of mathematicians to validate his results.

Is P equal to NP?

Roughly speaking, P is a set of relatively easy problems, and NP is a set that includes what seem to be very, very hard problems, so P = NP would imply that the apparently hard problems actually have relatively easy solutions.
