Heteroclinic solutions in singularly perturbed discontinuous differential equations: a non-generic case

Electronic Journal of Qualitative Theory of Differential Equations
We derive Melnikov type conditions for the persistence of heteroclinic solutions in perturbed slowly varying discontinuous differential equations. Opposite to [J. Differential Equations 400(2024), 314–375] we assume that the unperturbed (frozen) equation

Two-dimensional parabolic problem with a rapidly oscillating free term

MANAS: Journal of Engineering, 2019
Theaim of this paper is to construct regularized asymptotics of the solution of a two-dimensional partial differential equation of parabolictype with a small parameter for all spatial derivatives and a rapidlyoscillating free term.

Uniqueness of rapidly oscillating periodic solutions to a singularly perturbed differential-delay equation

Electronic Journal of Differential Equations, 2000
In this paper, we prove a uniqueness theorem for rapidly oscillating periodic solutions of the singularly perturbed differential-delay equation $varepsilon dot{x}(t)=-x(t)+f(x(t-1))$.
