Abstract

The goal of this paper is to establish a general framework for dynamic behaviors of coupled fractional-order stochastic dynamic systems of particles by using star-coupled models. In particular, the general mechanics on the dynamic behaviors related to the stochastic resonance (SR) phenomenon of a star-coupled harmonic oscillator subject to multiplicative fluctuation and periodic force in viscous media are established by considering couplings, memory effects, the occurring of synchronization linked to the occurring of SR induced. The multiplicative noise is modeled as dichotomous noise and the memory of viscous media is characterized by fractional power kernel function. By using the Shapiro-Loginov formula and Laplace transform, the analytical expressions for the first moment of the steady state response, the stability and relationship between the system response and the system parameters in the long-time limit in terms of systems'asymptotic stability are also established. All theoretical analyses are supported by the corresponding numerical simulations, and thus it seems that the results established in this paper would provide a possible fundamental mathematical framework for the study of Schumpeter's theory on the economic development under the innovation and capital paradigm and related disciplines. In particular, the framework established by this paper allows us at the first time logically concluding that in general, the ratio for SMEs grow up successfully is less than one third, this is consistent with what the market has been observed commonly, and the similar conclusion available from the existing literature today.
