Zoom seminar

Title: Some tame or wild Cantor dynamical systems Abstract: A topological dynamical system is a pair $(X,T)$ where $X$ is a compact metric spaces and $T$ is a group or semigroup acting continuously on $X$. One algebraic invariant of a such a dynamical system is the Ellis semigroup.  The Ellis semigroup $E(X,T)$ of a topological dynamical system is defined to be the compactification of the action $T$ in the topology of pointwise convergence on the space of all function $X^X$. …

Title: Nodal deficiency via equipartition energy functionals and the Dirichlet-to-Neumann map Abstract: A classic result in differential equations is that the nth eigenfunction of a Sturm-Liouville boundary value problem has precisely n-1 zeros. Courant’s nodal domain theorem provides a natural generalization of this result to higher dimensions, but it is generally not sharp. The lack of sharpness is measured by the “nodal deficiency” of an eigenfunction. Despite over a century of intensive study, this quantity is still not very well…

Title: Linear stability of slowly rotating Kerr spacetimes Abstract: I will describe joint work with Dietrich Häfner and András Vasy in which we study the asymptotic behavior of linearized gravitational perturbations of Schwarzschild or slowly rotating Kerr black hole spacetimes. We show that solutions of the linearized Einstein equation decay at an inverse polynomial rate to a stationary solution (given by an infinitesimal variation of the mass and angular momentum of the black hole), plus a pure gauge term. The proof uses…
