Propagation and propagation failure of waves on excitable tree networks — Nikos Kouvaris1, •Thomas Isele2, Alexander Mikhailov3, and Eckehard Schöll2 — 1Department of Physics, University of Barcelona, Marti i Franques 1, 08028, Barcelona, Spain — 2Institut für theoretische Physik, Technische Universität Berlin, Hardenbergstraße 36, 10623 Berlin, Germany — 3Department of Physical Chemistry, Fritz Haber Institute of the Max Planck Society, Faradayweg 4-6, 14195 Berlin, Germany
We study the properties of pulse solutions on excitable tree networks by means of numerical (simulation and continuation) as well as analytical methods. We focus on the dependence of the propagation velocity and the change of stability properties with respect to the branching ratio (i.e. degree) of the nodes. But we also consider different coupling strengths and the continuous (thermodynamic) limit of our model.
