Wilhelm Killing Kolloquium: Prof. Dr. Juan J. L. Velázquez (Universität Bonn): A free boundary problem of cell polarization
Thursday, 30.11.2023 14:15 im Raum M5
In this talk I will discuss the properties of a model of cell polarization
that describes the distribution of active receptors on the surface of a
cell. The model is a reaction diffusion system whose solutions approach
in a suitable scaling limit the solutions of a free boundary problem.
This limiting problem has many similarities with the classical obstacle
problem, but it has, as a distinctive feature, a mass conservation
property. As a result of this, the solutions of the problem exhibit
interesting pattern formation properties which do not appear in the
classical obstacle problem, and that will be discussed in detail. Further,
the behavior of the interfaces separating the polarized region from the
unpolarized region will be described.
