Bifurcation from a Homoclinic Orbit in Partial Functional Differential Equations

We consider a family of partial functional differential equations which has a homoclinic orbit asymptotic to an isolated equilibrium point at a critical value of the parameter. Under some technical assumptions, we show that a unique stable periodic orbit bifurcates from the homoclinic orbit. Our approach follows the ideas of Šil’nikov for ordinary differential equations and of Chow and Deng for...

Chaos in the Lorenz Equations: a Computer-assisted Proof

A new technique for obtaining rigorous results concerning the global dynamics of nonlinear systems is described. The technique combines abstract existence results based on the Conley index theory with computer-assisted computations. As an application of these methods it is proven that for an explicit parameter value the Lorenz equations exhibit chaotic dynamics. Introduction The purpose of this...

Nonsymmetric Lorenz Attractors from a Homoclinic Bifurcation

We consider a bifurcation of a flow in three dimensions from a double homoclinic connection to a fixed point satisfying a resonance condition between the eigenvalues. For correctly chosen parameters in the unfolding, we prove that there is a transitive attractor of Lorenz type. In particular we show the existence of a bifurcation to an attractor of Lorenz type which is semiorientable, i.e., ori...

A Homoclinic Orbit in a Planar Singular ODE - A Computer Assisted Proof

We consider a family of 2-dimensional ODEs of the form Δξ(z)z ′ = fξ(z) depending on a real parameter ξ which was investigated by Vladimirov [Rep. Math. Phys., 61 (2008), pp. 381–400]. In this system, there exist stationary points pξ which belong to the set of zeros of Δξ. We prove, using rigorous numerics, the existence of a homoclinic orbit to pξ for some parameter value ξ = ξh. Due to the si...

Homoclinic and heteroclinic orbits in a modified Lorenz system

This paper presents a mathematically rigorous proof for the existence of chaos in a modified Lorenz system using the theory of Shil’nikov bifurcations of homoclinic and heteroclinic orbits. Together with its dynamical behaviors, which have been extensively studied, the chaotic dynamics of the modified Lorenz system are now much better understood, providing a rigorous theoretic foundation to sup...
