Abstract

The network Kuramoto model is a celebrated model of coupled oscillators renowned for the complex self-organizational synchronization behaviour it exhibits with relatively simple dynamics. Much work has been done in the dynamical systems and control communities on predicting which model parameters lead to synchronization and which do not. I will be presenting an established method due to Dorfler, Chertkov, and Bullo for bounding the bifurcation point from above, my own variation on the method for bounding the bifurcation from below, a reformulation of partial synchronization predictions as a graph theoretical optimization problem, and will connect the questions we have about the Kuramoto model to well-studied questions in spectral graph theory and power engineering.
