Explore a 49-minute seminar on cell polarization presented by Barbara Niethammer from the University of Bonn. Delve into a model that couples diffusion equations in the inner cell with reaction-diffusion equations on the cell membrane. Discover how generalized obstacle-type problems are derived from certain scaling limits and learn about the global stability of steady states in these limit systems. Understand the parameter regime that triggers the onset of polarization. Gain insights from this collaborative research involving Anna Logioti, Matthias Roeger, and Juan Velazquez. Presented by the Society for Industrial and Applied Mathematics, this talk offers a deep dive into the mathematical analysis of partial differential equations in biological systems.
