Transition from the self-organized to the driven dynamical clusters

Singh, Aradhana; Jalan, Sarika - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 24, pp. 6655-6663

We study the mechanism of formation of synchronized clusters in coupled maps on networks with various connection architectures. The nodes in a cluster are self-synchronized or driven-synchronized, based on the coupling strength and underlying network structures. A smaller coupling strength...

Evolution of network structure by temporal learning

Jost, Jürgen; Kolwankar, Kiran M. - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 9, pp. 1959-1966

We study the effect of learning dynamics on network topology. A network of discrete dynamical systems is considered for this purpose and the coupling strengths are made to evolve according to a temporal learning rule that is based on the paradigm of spike-time-dependent plasticity. This...

Synchronization analysis of delayed complex networks with time-varying couplings

Li, Ping; Yi, Zhang - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 14, pp. 3729-3737

In this paper, a new method is presented to analyze the linear stability of the synchronized state in arbitrarily coupled complex dynamical systems with time delays. The coupling configurations are not restricted to the symmetric and irreducible connections or the non-negative off-diagonal...
