摘要 In this talk, we discuss the regularity and Liouville theorems of the axially symmetric (AS) Navier-Stokes (NS) equations. For the non-stationary case, some blow-up criteria and a priori estimates will be given. Besides, A result on “finite speed ASNS passing a cone will be introduced. For the stationary NS equations, some decay rates and a priori assumptions for proving vanishing results of D-solutions will be presented. We will see that there are still gaps to prove Liouville theorems of D-solutions in the whole space R^3 without extra assumptions. However, we can show Liouville theorems of D-solutions in some special unbounded domain such as in a slab and in a cylinder.
