Nature of weak generalized synchronization in chaotically driven maps

Area of Science:

• Dynamical Systems and Chaos Theory
• Nonlinear Dynamics
• Complex Systems Analysis

Background:

• Generalized synchronization is a phenomenon in coupled dynamical systems where one system (response) follows another (drive).
• Weak generalized synchrony is characterized by a unique but nondifferentiable relationship between drive and response dynamics.
• This phenomenon shares similarities with the formation of strange nonchaotic attractors in quasiperiodically driven systems.

Purpose of the Study:

• To investigate the geometric properties of limit sets in a chaotically driven monotone map exhibiting weak generalized synchronization.
• To analyze the fractal dimension of the set of zeros within this synchronization regime.
• To explore the stable and unstable sets and quantify the regularity of the coupling function.

Main Methods:

• Analytical and numerical examination of a chaotically driven monotone map.
• Calculation of the fractal dimension of the set of zeros.
• Analysis of stable and unstable sets.
• Measurement of the coupling function's regularity.

Main Results:

• The fractal dimension of the set of zeros in weak generalized synchronization was determined.
• The geometry of the limit set was characterized.
• Stability indices and dimension spectra of the equilibrium measure were analytically computed.

Conclusions:

• The study provides a detailed analysis of weak generalized synchronization in a specific dynamical system.
• Analytical and numerical methods were successfully employed to characterize the system's behavior.
• The findings contribute to the understanding of synchronization phenomena in complex systems.
