报告摘要:

In this article, we begin by reviewing some classical results on the existence and regularity theory of the three-dimensional incompressible Navier--Stokes system (denoted by $(NS)$). We then present our results on the global well-posedness of the three-dimensional anisotropic Navier--Stokes system ($(ANS)$), which has dissipation only in the $x_1$ and $x_2$ directions. In the third part of this article, we establish regularity criteria and well-posedness results for the system $(NS)$. We emphasize that the proofs of these results rely essentially on the anisotropic analysis developed in our study of $(ANS)$. Finally, we present our results on lower bound estimates for the analyticity radius of solutions to both $(NS)$ and $(ANS)$.
