Structure of Solutions and Dynamic Chaos in Nonlinear Differential Equations

The structure of solutions in nonlinear dissipative dynamical systems described by differential equations, including systems with chaotic behavior is considered. It is shown that the structure of the solutions in these systems is provided by either set of limit cycles, or tori, and is determined by the spectrum of Floquet Exponents. Important role in forming of structures play limit cycles having a complex but not complex conjugate Floquet Exponents. Examples of using the concept of the structure of solutions of nonlinear differential equations in the study of the formation of solitary traveling waves and the phenomenon of turbulence are presented.
