| Outline of Final Research Achievements |
In equilibrium systems, the concept of interfacial tension has already been established, and many phenomena can be mathematically formulated based on variational principle considering it. In nonequilibrium systems, such as those with nonuniform interfacial tension, however, we have not yet constructed definite formulation. In order to approach it, we studied on several systems such as a liquid droplet with anisotropic interfacial tension, a droplet in contact with the wedge-shaped substrate, interface deformed by the convection induced by surfactants on the surface.
