A computer-assisted argument is given, which provides existence proofs for periodic orbits in state-dependent delayed perturbations of ordinary differential equations (ODEs). Assuming that the unperturbed ODE has an isolated periodic orbit, we introduce a set of polynomial inequalities whose successful verification leads to the existence of periodic orbits in the perturbed delay equation. We present a general algorithm, which describes a way of computing the coefficients of the polynomials and…

Parameterization Method for State-Dependent Delay Perturbation of an Ordinary Differential Equation

TLDR
This work considers state-dependent delay equations (SDDE) obtained by adding delays to a planar ordinary differential equation with a limit cycle and shows that the SDDE admits solutions which resemble the solutions of the ODE.

Rigorous numerics for analytic solutions of differential equations: the radii polynomial approach

TLDR
This work derives the radii polynomials for some specific application problems, and gives a number of computer assisted proofs in the analytic framework on studying periodic solutions in Cartesian products of infinite sequence spaces.

Expansions in the delay of quasi-periodic solutions for state dependent delay equations

We consider several models of state dependent delay differential equations (SDDEs), in which the delay is affected by a small parameter. This is a very singular perturbation since the nature of the

In this paper, we develop computer-assisted techniques for the analysis of periodic orbits of ill-posed partial differential equations. As a case study, our proposed method is applied to the

The goal of this paper is to develop a KAM theory for tori with hyperbolic directions, which applies to Hamiltonian partial differential equations, even to some ill-posed ones. The main result has an

On polynomial forms of nonlinear functional differential equations

In this paper we study nonlinear autonomous retarded functional differential equations; that is, functional equations where the time derivative may depend on the past values of the variables. When
