报告题目: 3-D incompressible Navier-Stokes equations in the cylindrical coordinates

报告人: 刘彦麟 教授（北京师范大学）

摘要：We intend to study 3-D incompressible Navier-Stokes equations in the cylindrical coordinates. Here we do not limit us in the classical axisymmetric case, but the axisymmetric structure still plays a key role. For general initial data, we can expand them into Fourier series in $\theta$ variable. In particular, we prove the global existence of strong solutions if the initial data is of the form: $A(r,z)\cos N\theta +B(r,z)\sin N\theta$, provided that $N$ is large enough. This is based on joint work with Ping Zhang.
