Dynamics of mergers, bifurcation and chaos: A new framework

Gangopadhyay, Partha - In: Physica A: Statistical Mechanics and its Applications 403 (2014) C, pp. 293-307

This paper is motivated by a gap in the existing literature on mergers since no attempt has been successfully made to consider endogenous multiple mergers that trigger reciprocal mergers, which in turn fuel further mergers and the process continues ad infinitum. The precise contribution of this...

Fine structure in the scaling of type-I intermittency bifurcations

S. Cavalcante, Hugo L.D. de; Leite, J.R. Rios - In: Physica A: Statistical Mechanics and its Applications 342 (2004) 1, pp. 356-362

Tangent bifurcations in maps with type-I intermittency have been studied numerically and oscillations in the statistical properties were found as functions of the control parameter. The average length of laminar events, the Lyapunov exponent and the averages of the dynamical variable were...

Controlling chaos in an economic model

Chen, Liang; Chen, Guanrong - In: Physica A: Statistical Mechanics and its Applications 374 (2007) 1, pp. 349-358

A Cournot duopoly, with a bounded inverse demand function and different constant marginal production costs, can be … features of the model, we show how bifurcation and chaos can be controlled via the delayed feedback control method. We then … implications of the chaos control strategies described in the paper. …

The defocusing mechanism of isochronous resonances

Carvalho, R. Egydio de; Favaro, G.M. - In: Physica A: Statistical Mechanics and its Applications 350 (2005) 2, pp. 173-182

We present a numerical study concerning the defocusing mechanism of isochronous resonance island chains in the presence of two permanent robust tori. The process is initialized and concluded through bifurcations of fixed points located on the robust tori. Our approach is based on a Hamiltonian...

Bifurcation in neuronal networks with hub structure

Kitajima, Hiroyuki; Kurths, Jürgen - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 20, pp. 4499-4508

We investigate bifurcations in neuronal networks with a hub structure. It is known that hubs play a leading role in characterizing the network dynamical behavior. However, the dynamics of hubs or star-coupled systems is not well understood. Here, we study rather subnetworks with a star-like...
