Area of Science:

  • Theoretical Biology
  • Dynamical Systems Theory
  • Biophysics

Background:

  • Complex dynamics of replicating biomolecules are crucial for understanding life.
  • Lotka-Volterra models are widely used to study population dynamics and ecological interactions.
  • Chaotic behavior and fractal structures are observed in various biological systems.

Purpose of the Study:

  • To develop a general system of high-order differential equations for complex biomolecular dynamics.
  • To investigate symmetry relations and coordinate transformations for replication systems.
  • To analyze chaotic attractors and fractal tori in generalized Lotka-Volterra models.

Main Methods:

  • Derivation of high-order differential equations for replication systems.
  • Application of symmetry relations and coordinate transformations.
  • Analysis of chaotic regimes, fractal tori, and Lyapunov exponents in Lotka-Volterra models and replicator networks.

Main Results:

  • Three chaotic attractors in 3D Lotka-Volterra equations represent cross-sections of a single chaotic regime.
  • A fractal torus in a generalized Lotka-Volterra model is linked to a chaotic attractor.
  • Analytic expressions for Lyapunov exponents were derived, and Lyapunov spectra for pathways into chaos were calculated.

Conclusions:

  • The study unifies observed chaotic attractors within a single chaotic regime.
  • It demonstrates the existence of complex bifurcations and diverse dynamical pathways in generalized Lotka-Volterra systems.
  • The findings provide a deeper understanding of chaotic dynamics in biomolecular replication systems.
