Maximum Principle for Optimal Control of Neutral Stochastic Functional Differential Systems [PDF]

open access: yes, 2013
In this paper, the optimal control problem of neutral stochastic functional differential equation (NSFDE) is discussed. A class of so-called neutral backward stochastic functional equations of Volterra type (VNBSFEs) are introduced as the adjoint ...

Numerical Algorithm for Nonlinear Delayed Differential Systems of $n$th Order

open access: yes, 2019
The purpose of this paper is to propose a semi-analytical technique convenient for numerical approximation of solutions of the initial value problem for $p$-dimensional delayed and neutral differential systems with constant, proportional and time varying

An averaging principle for neutral stochastic functional differential equations driven by Poisson random measure [PDF]

open access: yes, 2016
In this paper, we study the averaging principle for neutral stochastic functional differential equations (SFDEs) with Poisson random measure. By stochastic inequality, Burkholder-Davis-Gundy’s inequality and Kunita’s inequality, we prove that the ...

Bogdanov-Takens bifurcation for neutral functional differential equations

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we consider a class of neutral functional differential equations (NFDEs). First, some feasible assumptions and algorithms are given for the determination of Bogdanov-Takens (B-T) singularity.

Periodic solutions of convex neutral functional differential equations [PDF]

open access: yesTohoku Mathematical Journal, 2000
In this paper, the authors study the existence of periodic solutions to neutral differential equations. It is proved that for convex neutral functional-differential equations of \(D\)-operator type with finite (or infinite) delay and hyperneutral functional-differential equations with finite delay the problem of the existence of periodic solutions is ...

Invariant Measures for Dissipative Dynamical Systems: Abstract Results and Applications [PDF]

open access: yes, 2012
In this work we study certain invariant measures that can be associated to the time averaged observation of a broad class of dissipative semigroups via the notion of a generalized Banach limit.

Oscillation Theorems for Second-Order Quasilinear Neutral Functional Differential Equations

open access: yesAbstract and Applied Analysis, 2012
New oscillation criteria are established for the second-order nonlinear neutral functional differential equations of the form (r(t)|z′(t)|α−1z′(t))’+f(t,x[σ(t)])=0, t≥t0, where z(t)=x(t)+p(t)x(τ(t)), p∈C1([t0,∞),[0,∞)), and α≥1.
