Energy Function for Direct Products of Discrete Dynamical Systems
نویسندگان
چکیده
This paper is devoted to the construction of an energy function, i.e. a smooth Lyapunov whose set critical points coincides with chain-recurrent dynamical system — for cascade that direct product two systems. One multipliers structurally stable diffeomorphism given on two-dimensional torus, non-wandering consists zero-dimensional non-trivial basic without pairs conjugated and fixed source sink, second one identical mapping real axis. It was previously proved if contains set, as under consideration has, then such does not have namely, any function will outside set. For mapping, constant entire line. In this paper, it shown absence sufficient condition systems, is, in some cases possible select way function.

چکیده در این پایاننامه ابتدا فضاهای متریک فازی را به صورت مشاهدهگرایانه بررسی میکنیم. فضاهای متریک فازی و توپولوژی تولید شده توسط این متریک معرفی شدهاند. سپس بر اساس فضاهایی که در فصل اول معرفی شدهاند آشوب توپولوژیکی، مینیمالیتی و مجموعههای متقاطع در شیوههای مختلف بررسی شده- اند. در فصل سوم مفهوم مجموعههای جاذب فازی به عنوان یک مفهوم پایهای در سیستمهای نیم-دینامیکی نسبی، تعریف شده است. ...

In this paper we construct a one-dimensional map with a non hyperbolic fixed point at zero for which the orbits converging to zero and the solution of the associated variational equation can be determined explicitly. We extend the construction to parameterized systems where the fixed point undergoes bifurcations. Applications are indicated to heteroclinic orbits that connect a hyperbolic to a n...
متن کاملstudy of bifurcation and hyperbolicity in discrete dynamical systems
bifurcations leading to chaos have been investigated in a number of one dimensional dynamical systems by varying the parameters incorporated within the systems. the property hyperbolicity has been studied in detail in each case which has significant characteristic behaviours for regular and chaotic evolutions. in the process, the calculations for invariant set have also been carried out. a bro...

in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
15 صفحه اولDiscrete Dynamical Systems: Maps
Many physical systems displaying chaotic behavior are accurately described by mathematical models derived from well-understood physical principles. For example, the fundamental equations of fluid dynamics, namely the Navier–Stokes equations, are obtained from elementary mechanical and thermodynamical considerations. The simplest laser models are built from Maxwell’s laws of electromagnetism and...
