Title: On the shape of the positivity region for a free boundary problem describing cell polarization
Given a smooth bounded domain in three dimensional space, we study a mass-constrained obstacle-type problem posed on its boundary. This problem has been proposed as a model for cell polarization by Matthias Röger, Barbara Niethammer and Juan J. L. Velázquez in 2020. We describe in detail the shape of the positivity set in the generic case where the signal is a Morse function on the surface. As a consequence, we derive regularity of the free boundary for small positive mass. We also obtain scaling limits in more general settings, and we illustrate behavior where the signal is non-generic by way of some examples.
This is joint work with Barbara Niethammer and Juan J. L. Velázquez

Title: Resonant solutions to an Euler-Poisson equation
We study the shape of a liquid in two dimensions circling around the common center of mass with some external particle. First, we consider the non-resonant case as proposed in an article by Diego Alonso-Orán, Bernhard Kepka and Juan J. L. Velázquez in 2024. Then we will see what differs in the case of resonance.
