## Is Poincare Conjecture solved?

as of December 21, 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.

## Who made the Poincare Conjecture?

Henri Poincaré

This question turned out to be extraordinarily difficult. Nearly a century passed between its formulation in 1904 by Henri Poincaré and its solution by Grigoriy Perelman, announced in preprints posted on ArXiv.org in 2002 and 2003.

**Why is the Poincare Conjecture important?**

So work on the Poincare conjecture has led to a deeper understanding of 3-manifolds in general. Not only that, but Perelman’s work introduced important techniques which can now be used on other problems. The fundamental idea behind algebraic topology is to translate topological problems into algebraic problems.

**What are the 7 math Millennium Problems?**

Clay “to increase and disseminate mathematical knowledge.” The seven problems, which were announced in 2000, are the Riemann hypothesis, P versus NP problem, Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier-Stokes equation, Yang-Mills theory, and Poincaré conjecture.

### Who solved P vs NP?

Now, a German man named Norbert Blum has claimed to have solved the above riddle, which is properly known as the P vs NP problem. Unfortunately, his purported solution doesn’t bear good news. Blum, who is from the University of Bonn, claims in his recently published 38-page paper that P does not equal NP.
