It is difficult to find an exact solution to a general nonlinear equation, only an approximate solution can be found, and it is even more difficult to find a solution to this Ns equation.

Wei Dongyi has made a series of important research progress in the regularity of three-dimensional Navier-Stokes equation and the linear damping of two-dimensional incompressible Euler equation. He also cooperated with others and made great achievements in the study of random matrix theory. By February 20 19, 19 Wei Dongyi had published more than ten papers in international mathematical journals. Therefore, his achievements in mathematics are internationally recognized.

Wei Dongyi, 199 1 born, is currently an assistant professor in Peking University and a researcher in the Department of Differential Equations of Peking University Institute of Mathematical Sciences.
