Probabilistic methods for deterministic systems (on networks) — •Frank Hellmann — Potsdam-Institut für Klimafolgenforschung (PIK), Potsdam, Detuschland

I discuss how we use probabilistic, sampling based methods to understand and uncover dynamic properties of complex systems on networks. The motivating example are Kuramoto oscillators with inertia, which we interpret as a simple example of power grids.

Concretely I show how the underlying network topology leaves a quantifiable imprint on the dynamical properties of the overall system, in particular its ability to return to or stay close to synchronization, and how we can identify novel asymptotic states that are only accessible by perturbations at specific nodes.
