چکیده

We show that the map part of the discrete Conley index carries information which can be used to detect the existence of connections in the repeller-attractor decomposition of an isolated invariant set of a homeomorphism. We use this information to provide a characterization of invariant sets which admit a semi-conjugacy onto the space of sequences on K symbols with dynamics given by a subshift. These ideas are applied to the Henon map to prove the existence of chaotic dynamics on an open set of parameter values.

Computing specific isolating neighborhoods

A major challenge in applying the Conley index theory to a given dynamical system is to find isolating neighborhoods of the invariant sets of interest. In this paper we describe a computational method which allows for the efficient construction of isolating neighborhoods. As an example we compute an isolating neighborhood of a heteroclinic orbit connecting a fixed point to a period two point in...

A Rigorous Numerical Method for the Global Analysis of Infinite-Dimensional Discrete Dynamical Systems

We present a numerical method to prove certain statements about the global dynamics of infinite dimensional maps. The method combines set-oriented numerical tools for the computation of invariant sets and isolating neighborhoods, the Conley index theory and analytic considerations. It not only allows for the detection of a certain dynamical behaviour, but also for a precise computation of the c...

On Detecting of Chaotic Dynamics via Isolating Chains

We show in the paper the method of isolating chains in proof of chaotic dynamics. It is based on the earlier notion of an isolating segment but gives more powerful tool for exploring dynamics of periodic ODE’s. As an application we show that the processes generated by the equations in the complex plane ż = zk + eiφtz, where k ≥ 3 is an odd number and φ is close to 0, has chaotic behaviour.

On Geometric Detection of Periodic Solutions and Chaotic Dynamics

In this note we sketch some results concerning a geometric method for periodic solutions of non-autonomous time-periodic differential equations. We give the definition of isolating chain and we provide a theorem on the existence of periodic solutions inside isolating chains. We recall some results on existence of chaotic dynamics which can be proved by the theorem. We provide several examples o...

The homotopy Analysis Method in bifurcation Analysis of Delay differential equations

In this paper we apply the homotopy analysis method (HAM) to study the van der Pol equation with a linear delayed feedback. The paper focuses on the calculation of periodic solutions and associated bifurcations, Hopf, double Hopf, Neimark-Sacker, etc. In particular we discuss the behavior of the systems in the neighborhoods of double Hopf points. We demonstrate the applicability of HAM to the a...
