Filippov flows and mean-field limits in the kinetic singular Kuramoto model

D Poyato - arXiv preprint arXiv:1903.01305, 2019 - arxiv.org
The agent-based singular Kuramoto model was proposed in [60] as a singular version of the
Kuramoto model of coupled oscillators that is consistent with Hebb's rule of neuroscience. In …
