Heteroclinic orbits arising from coupled Chua’s circuits. (English) Zbl 1082.34036

This paper proves existence of traveling waves for a system of partial differential equations modelling cellular neural networks (traveling waves were already observed numerically). The problem is reduced to look for heteroclinic orbits of a system of three ordinary differential equations depending parametrically on the speed of the wave. Using a singular perturbation type approach, heteroclinic orbits are rigourously proved for large values of the speed.
