Abstract:

This paper discusses the stability of theoretical solutions for nonlinear multi-variable delay perturbation problems(MVDPP)of the form x′(t)=f(x(t), x(t-τ₁(t)), …, x(t-τ_m(t)), y(t), y(t-τ₁(t)), …, y(t-τ_m(t))), and εy′(t)=g(x(t), x(t-τ₁(t)), …, x(t-τ_m(t)), y(t), y(t-τ₁(t)), …, y(t-τ_m(t))), where 0<ε≪1. A sufficient condition of stability for the systems is obtained. Additionally we prove the numerical solutions of the implicit Euler method are stable under this condition.
