Title: Grain boundary motion with time-dependent misorientation and mobility effects
Abstract: In my talk, I will present a model of grain boundary motion with time-dependent misorientation and mobility effects. Dynamics of grain boundaries play an important role in defining the materials properties of polycrystals. The model, considered in the talk, is given by the system of partial differential equations, and is derived using energetic variational principle. Next, I will present the analysis of the model for the grain boundary motion. The key ingredient of the analysis is the so-called monotonicity formula of Huisken's type. Moreover, to treat the time-dependent mobility, we use the modified Gauss kernel to the monotonicity formula.
