Spurious Numerical Solutions of Delay Differential Equations
Keywords:
Spurious solution, Asymptotic behavior, Delay differential equation.Abstract
This paper deals with the relationship between asymptotic behavior of the numerical solution and that of the true solution itself for fixed step-sizes. The numerical solution is viewed as a dynamical system in which the step-size acts as a parameter. We present a unified approach to look for bifurcations from the steady solutions into spurious solutions as step-size varies.
