Abstract

The presence of the power-law memory is a significant feature of many natural (biological, physical, etc.) and social systems. Continuous and discrete fractional calculus is the instrument to describe the behavior of systems with the power-law memory. The existence of chaotic solutions is an intrinsic property of nonlinear dynamics (regular and fractional). The behavior of fractional systems can be very different from the behavior of the corresponding systems with no memory. Finding periodic points is essential for understanding regular and chaotic dynamics. Fractional systems do not have periodic points except for fixed points. Instead, they have asymptotically periodic points (sinks). There have been no reported results (formulae) that would allow calculations of asymptotically periodic points of nonlinear fractional systems so far. In this paper, we derive the equations that allow calculations of the coordinates of the asymptotically periodic sinks.
