Abstract

Abstract: In this paper, we consider an array of FitzHugh-Nagumo (FHN) systems with R close neighbors. Each element ( j ) connects to another ( m ) and its 2 R neighbors. Shifting these neighbors produces particular phenomena such as chimera and multi-chimera. Step traveling chimera is observed for a time dependent shift. Results show that, basing oneself on both shift parameter m and close neighbors R, a full control on the chimera dynamics of the network can be ensured.
