Navier-Stokes equation, Navier-Stokes equation, NS equation, describes the motion equation of viscous incompressible fluid momentum conservation , originally proposed by Navier in 1827, only considers the flow of incompressible fluid. Poisson proposed the equation of motion for compressible fluids in 1831, and in 1845 St. Venant and Stokes independently proposed equations with constant viscosity coefficients, but they were collectively referred to as Navier-Stokes equations. The existence problem of the smooth solution of the NS equations in 3D space is set as one of the seven Millennium Prize problems by the American Cray Institute of Mathematics , which is the expression of the NS equations on Baidu Encyclopedia.
In the past few days, I have seen several math gods say that if Wei Shen solves the Navier-Stokes equation, Fields Medal will definitely be handed. Wei Shen has made corresponding results on the Navier-Stokes equation, and published them in "ARVIX" and "Journal of Mathematical Analysis and Applications" in 2015 and 2016 respectively, but the paper has the same name:
"Regularity" criterion to the axially symmetric Navier–Stokes equations" page 12, translated into Chinese is "regularity criterion for axially symmetric Navier-Stokes equations", knowledgeable friends can take a look, by the way, judge Wei Shen's mathematics Level, I silently drifted past. The body of
is as follows:
