Outline of Final Research Achievements |
We consider the initial boundary value problems for incompressible Navier-Stokes equations in half space and perturbed half space. We proved the time decay estimates for the solutions in weighted Lp space. We also consider the semilinear heat equations and dissipative wave equations in two dimension exterior domains. We showed the L2 boundedness with respect to the space and time valuables of the solutions for initial data in the Hardy space.
