This talk presents a recent nonlinear stability result in this context. Starting with a discussion of stabilizing mechanisms in the linearized Vlasov-Poisson equations near a class of homogeneous equilibria on R^3, we will see how both oscillatory and damping effects arise, and sketch how these mechanisms imply a nonlinear stability result in the specific setting of the Poisson equilibrium. This is based on joint work with A. Ionescu, B. Pausader and X. Wang.

14.03.2024 16:15, Spiegelgasse 5, Room 05.002 Tumbling Downhill along a Given Curve Tags: TAG Events Perlenkolloquium, TAG Events DMI]]>A cylinder will roll down an inclined plane in a straight line. A cone will wiggle along a circle on that plane and then will stop rolling. We ask the inverse question: For which curves drawn on the inclined plane $\real^2$ can one chisel a shape that will roll downhill following precisely this prescribed curve and its translationally repeated copies?

This is a nice, and easy to understand problem, but the solution is quite interesting.

(Based on work mostly with Y. Sobolev and T. Tlusty. After a Nature paper, Solid-body trajectoids shaped to roll along desired pathways, August 2023.)
