Outline of Final Research Achievements |
I have studied regularity and asymptotic behavior of solutions for the Navier-Stokes equations, which describes the motion of viscous incompressible flows such as the atmosphere and the water. In this research project, I have worked on the two problems. The first problem is an axisymmetric solution. I have constructed global unique axisymmetric solutions in an exterior domain subject to the slip boundary condition for decaying and sufficiently smooth initial data. The second is a non-decaying solution. I have constructed local-in-time unique solutions in an exterior domain in a space of bounded functions. For the two-dimensional case, I have proved that global unique solutions exist for bounded initial data with a finite Dirichlet integral.
