Collocation schemes for periodic solutions of neutral delay differential equations [PDF]

open access: yes, 2005
We introduce two collocation schemes for the computation of periodic solutions of neutral delay differential equations (NDDEs): one based on a direct discretisation of the underlying NDDE, and one based on a discretisation of a related delay differential

Almost sure exponential stability of the Euler–Maruyama approximations for stochastic functional differential equations [PDF]

open access: yes, 2011
By the continuous and discrete nonnegative semimartingale convergence theorems, this paper investigates conditions under which the Euler–Maruyama (EM) approximations of stochastic functional differential equations (SFDEs) can share the almost sure ...

On a class of first order nonlinear functional differential equations of neutral type [PDF]

open access: yes, 1987
Consider the neutral differential equation ddt [y(t) + py(t − τ)] + qy(t − σ) = 0, t ≧ t0 (∗) where p, q, τ, and σ are real numbers. Then a necessary and sufficient condition for the oscillation of (∗) is that the characteristic equation λ + pλe−λτ + qe ...

Positive periodic solutions of a neutral functional differential equation with multiple delays [PDF]

open access: yes, 2017
summary:This paper deals with the existence of positive $\omega $-periodic solutions for the neutral functional differential equation with multiple delays $$(u(t)-cu(t-\delta ))'+a(t) u(t)=f(t, u(t-\tau _1), \cdots , u(t-\tau _n)).$$ The essential ...
