Abstract
This paper is concerned with the analytic and numerical dissipativity of nonlinear neutral delay differential equations (NDDEs) of the form y′(t)=F(y(t),G(y(t−τ),y′(t−τ))). The basic idea is to reformulate the original problem eliminating the dependence on the derivative of the solution in the past values. A dissipativity criteria for nonlinear NDDEs is given. Dissipativity properties of one-leg θ-methods and linear θ-methods for the underlying systems are investigated. It is shown that, for , both one-leg θ-method and linear θ-method are dissipative. Numerical examples illustrate the theoretical results.
