Delay differential equations (DDEs) are infinite-dimensional systems, so even a scalar, unforced nonlinear DDE can exhibit chaos. Lyapunov exponents are indicators of chaos and can be computed by comparing the evolution of infinitesimally close trajectories. We convert DDEs into partial differential equations with nonlinear boundary conditions, then into ordinary differential equations (ODEs) using the Galerkin projection. The solution of the resulting ODEs approximates that of the original DDE…

Low-Dimensional Galerkin Approximations of Nonlinear Delay Differential Equations

This article revisits the approximation problem of systems of nonlinear delay differential equations (DDEs) by a set of ordinary differential equations (ODEs). We work in Hilbert spaces endowed with

Approximating Lyapunov exponents and Sacker–Sell spectrum for retarded functional differential equations

A numerical method is proposed to approximate quantities, based on the reduction to finite dimension of the evolution family associated to the system, to which a classic discrete QR method is then applied.

We study the chaotic attractors of a delay differential equation. The dimension of several attractors computed directly from the definition agrees to experimental resolution ~vith the dimension

Galerkin approximations with embedded boundary conditions for retarded delay differential equations

The presented results clearly demonstrate that the equivalent boundary condition-free PDE formulation accurately captures the dynamic behaviour of the original DDE system and facilitates the application of control theory developed for systems governed by ODEs.
