Applied Mathematics Seminar, Fall 2019

## Mondays 4:00 PM - 5:00 PM, LCB 215

• This seminar can be taken for credit: Students can get 1-3 credits by registering to the Applied Math Seminar class Math 7875 Section 010 for Fall 2019. Students should talk to the seminar organizer before taking it for a credit. Grading is based on attendance and giving a talk by presenting an applied-mathematics paper (not necessarily your own). Student talks will be appropriately labeled to distinguish them from visitor talks. The seminar organizer is available to review your slides, for dry-runs etc.
• Please direct questions or comments about the seminar (or its class) to Yekaterina Epshteyn (epshteyn (at) math.utah.edu)
• Talks are announced through the applied-math mailing list. Please ask the seminar organizer for information about how to subscribe to this list.

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.
