Existence of traveling wave solutions in nonlinear delayed cellular neural networks. (English) Zbl 1154.34364
Summary: This paper is concerned with the existence of traveling wave solutions of cellular neural network systems distributed in the one-dimensional lattice $\Bbb Z$. The dynamics of each given cell depends on itself and its nearest right neighbor cell where delays exist in self-feedback and neighborhood interaction. Under appropriate assumptions, we can prove the existence of traveling wave solutions whose output function is not piecewise linear.
