Research Subject

Mathematical Analysis on Differential Equations descrbing Nonlinear Diffusive Phenomena

Current Research

Various differential equations have been proposed with the purpose to model phenomena in nature such as motion of fluid, crystal growth and to handle problems in technology for example in image processing. My major research topic is nonlinear diffusion equations which form an important class of partial differential equations. ( A partial differential equation is a differential equation having several independent variables.) My particular interest lies in solvability of partial differential equations under given conditions and in tracking behavior of solutions in a rigorous mathematical framework even if solutions develop singularities.
