| Outline of Final Research Achievements |
In this research, our aim is to analyze the domain dependency of the Green function and the eigenvalues of the Stokes equations with the Dirichlet boundary condition.
As a result, we succeeded to establish the Hadamard variational formula for the Green function for the velocity and pressure under the general second order domain perturbations. Moreover, we composed the variational formula for the multiple eigenvalues, and we succeeded to apply that formula to clarify the topological type of the domain.
