Takashi Kagaya - Division of Fundamental mathematics, Institute of Mathematics for Industry, Kyushu University
Sep 6, 2019 - 10:00am to 11:00am
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 025
We consider the flow of hyper-surface generating 90 degree contact angle on the boundary of a bounded domain. The motion is governed by the mean curvature flow equation. For this free boundary problem, the mean curvature flow should "pop" upon tangential contact with the boundary of the domain.... read more

Keisuke Takasao - Department of Mathematics, Kyoto University
Sep 4, 2019 - 5:00pm to 6:00pm
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 025
We study the mean curvature flow with given non-smooth transport term, in suitable Sobolev spaces. In 2010, Liu, Sato and Tonegawa showed a global-in-time existence of the Brakke flow by using the Allen-Cahn equation. The most difficult part of the proof is the estimates of the positive part of the... read more

Masashi Mizuno - Department of Mathematics, Nihon University
Sep 3, 2019 - 3:00pm to 4:00pm
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 026
To study the dynamics of grain boundaries is important to understand the mechanism for defining the material properties of polycrystals. In my talk, I will present a model of grain boundary motion with time-dependent misorientation and mobility effects. First, I derive the system of partial... read more
