Abstract
A computational bifurcation diagram of nonlinear fractional order systems may provide a visual representation of understanding possible dynamics in a wide range of system parameters and associated fractional orders. This observed phenomenon has sparked new interest in the question of mathematically sound and rigorous proofs of the existence of such dynamics. No mathematical foundation for the stability of bifurcations has been developed for fractional order systems, and roughly computational attractors are less understood. A famous hidden memory chaotic attractor is the typical class of attractor that does occur in nonlinear fractional order systems without any known bifurcations of any existing attractors. It has been found that such attractors are fundamental and localized with nonlinear fractional-order systems with no equilibrium points. Many intuitive examples are constructed, and the governing dynamics are hidden memory chaotic attractors.
