Synchronized clusters in coupled map networks: Stability analysis
Sarika Jalan, R. E. Amritkar, Chin-Kun Hu
We study self-organized (s-) and driven (d-) synchronization in coupled map networks for some simple networks, namely two and three node networks and their natural generalization t…
Self-organized and driven phase synchronization in coupled map scale free networks
Sarika Jalan, R. E. Amritkar
As a model of evolving networks, we study coupled logistic maps on scale free networks. For small coupling strengths nodes show turbulent behavior but form phase synchronized clust…
Estimation of Initial Conditions and Secure Communication
Anil Maybhate, R. E. Amritkar, D. R. Kulkarni
We estimate the initial conditions of a multivariable dynamical system from a scalar signal, using a modified Newton-Raphson method incorporating the time evolution. We can estimat…
Stochastic Coherence in Coupled Map Lattices
Manojit Roy, R. E. Amritkar
We report in details the observations of structures in coupled map lattice during its chaotic evolution, both in one and two dimension, driven by identical noise on each site (by a…
