Chaos in networks with time-delayed couplings

Abstract: Networks of nonlinear units coupled by time-delayed signals can show chaos. In the limit of long delay times, chaos appears in two ways: strong and weak, depending on how the maximal Lyapunov exponent scales with the delay time. Only for weak chaos, a network can synchronize completely, without time shift. The conditions for strong and weak chaos and synchronization in networks with multiple delay times are investigated.

“…The effect of the ratio between different delay times on the synchronization properties of two mutually coupled chaotic lasers was recently investigated in [22]. Here we concentrate on the multiplicity of stable periodic regimes generated by the mutually coupled OEOs rather than their synchronization efficiency as they are chaotic.…”

“…This process is very similar to a Bernoulli map [16,17], X n+1 =(aX n ) mod 1, which is non-chaotic for a<1. The variable X n stands not for the neuronal response latency L, but for L'(L n ).…”

“…Time delay in neural networks emanates from the finite speed of the transmission of an action potential between two neurons where the propagation velocity of an action potential varies between 1 to 100 mm/ms depending on the diameter of the axon and whether the fibers are myelinated or not [Koch, 1999]. The influence of delay on the dynamics on networks has been investigated by several authors Kestler et al, 2008;Kinzel et al, 2009;Englert et al, 2010;Zigzag et al, 2010;Flunkert et al, 2010;Rosin et al, 2010;Englert et al, 2011;Kanter et al, 2011b;Heiligenthal et al, 2011;Flunkert et al, 2013b;Popovych et al, 2011;Lücken et al, 2013;Kinzel, 2013;D'Huys et al, 2013;Kantner and Yanchuk, 2013;D'Huys et al, 2014] Depending on the context, delay can play a constructive or a destructive role. For example, time-delayed feedback control (TDFC) is a well established control method to control unstable periodic orbits embedded in chaotic attractors as well as unstable fixed points [Pyragas, 1992;Ahlborn and Parlitz, 2004;Rosenblum and Pikovsky, 2004;Hövel and Schöll, 2005;Schöll and Schuster, 2008;Grebogi, 2010].…”

“…In the following, the MSF is derived for a delay-coupled network [Dhamala et al, 2004;Choe et al, 2010;Kinzel et al, 2009;Heiligenthal et al, 2011;Kinzel, 2013;D'Huys et al, 2013]. If the delay time is set to zero, the results of [Pecora and Carroll, 1998] for a network without delayed coupling are recovered.…”
