This study investigates the fractional-order Bogoyavlenskii dynamical system, examining how memory effects influence system behavior and the transitions between regular and chaotic dynamics. The researchers analyze how varying the fractional-order derivative parameter affects the system's stability, bifurcations, and emergence of chaotic attractors, demonstrating that fractional calculus introduces memory-dependent properties absent in classical integer-order models.


Understanding memory effects in nonlinear dynamical systems has applications in modeling complex phenomena in fluid dynamics, plasma physics, and nonlinear wave propagation. The findings could improve predictions in systems where historical states influence current behavior, such as material science and certain engineering applications.
