二、主讲人:
王文栋
三、摘要:
In this topic we will focus on Liouville theorems and classication of solutions for the steady Navier-Stokes equations. Firstly, we will review some basic tools and techniques including Bogovskii maps; Secondly, we describe the progress of some two-dimensional Navier-Stokes equations, including the Liouville theorem, the decay or classification estimation of solutions; Once again, for the three-dimensional equations, we will describe some major developments, including some uniqueness results depending on velocity, total pressure, or potential functions; Finally, we will discuss it from decay estimates or different regions. This is a series of joint work with Seregin, J. Wu et al.
