I am interested in partial differential equations which are relation to variational problems. So I especially study the gradient flow of the total variation that describes a process to remove a noise from the original image in the image processing. Since the total variation flow has a strong singularity, the subdifferential for convex functions and the nonlinear semigroup theory are useful to analyze its solvability and asymptotic behavior. These days I have an interest in the thin domain problems.
