Basically, prove that A=C, the Russians have proved A=B, b = C, and then stopped. China people are shameless, so they wrote an A=C card. Said he capped it and caught 30%.
The main contributions were made by Hamilton and perelman. The job of Zhu Xiping and Cao Huaidong is to fill a big loophole. Regarding mathematics, the contribution of China people is actually exaggerated. For example, Qiu Chengtong is not the "home" of foreign countries.
Poincare conjecture is a conjecture put forward by French mathematician Poincare, and it is an award provided by Cray Institute of Mathematics. Millennium prize puzzle. The three-dimensional situation was solved by Russian mathematicians? Grigory perelman proved around 2003.
In 2006, the mathematical community finally confirmed that perelman's proof solved Poincare's conjecture. Poincare conjecture is one? The proposition with basic significance in topology will help people to study three-dimensional space better, and the result will deepen people's understanding of manifold properties.
Simply put, a closed three-dimensional manifold is a three-dimensional space without boundaries; Simple connectivity means that every closed curve in this space can shrink to a point continuously, or in a closed three-dimensional space, if every closed curve can shrink to a point, then this space must be a three-dimensional sphere.
