On the control of opinion dynamics in social networks

Liu, Zhihong; Ma, Jianfeng; Zeng, Yong; Yang, Li; … - In: Physica A: Statistical Mechanics and its Applications 409 (2014) C, pp. 183-198

This paper presents a framework to analyze the controllability of opinion dynamics in social networks using DeGroot model (DeGroot, 1974). We show how the opinion, or attitude about some common questions of interest in a population can be controlled by a committed node who consistently...

Cluster projective synchronization between community networks with nonidentical nodes

Wu, Zhaoyan; Fu, Xinchu - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 23, pp. 6190-6198

In this paper, cluster projective synchronization between community networks with nonidentical nodes is investigated. Outer synchronization between two identical or nonidentical complex networks has been extensively studied, in which all the nodes synchronized each other in a common manner....

Controlling chaos in systems of coupled oscillators

Núñez, M.; Mato, G. - In: Physica A: Statistical Mechanics and its Applications 307 (2002) 3, pp. 315-330

We study the dynamical behavior of a one-dimensional network of phase oscillators, displaying a variety of cluster or traveling wave solutions, either stable or unstable according to the type of interaction function. For some range of parameters these solutions coexist with a chaotic attractor....

A comparative investigation of controlling chaos in a Rössler system

Braun, T; Heisler, I.A - In: Physica A: Statistical Mechanics and its Applications 283 (2000) 1, pp. 136-139

We investigate the issue of controlling chaos by performing perturbations in the variables and in the parameters of an experimental Rössler system. A comparative analysis of the bifurcation structure induced by the two kinds of perturbations is presented.
