Oscillations for Neutral Functional Differential Equations [PDF]

open access: yesThe Scientific World Journal, 2014
We will consider a class of neutral functional differential equations. Some infinite integral conditions for the oscillation of all solutions are derived. Our results extend and improve some of the previous results in the literature.

Numerical solutions of neutral stochastic functional differential equations [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2008
This paper examines the numerical solutions of neutral stochastic functional differential equations (NSFDEs) $d[x(t)-u(x_t)]=f(x_t)dt+g(x_t)dw(t)$, $t\geq 0$.

Attractivity for Neutral Functional Differential Equations [PDF]

open access: yesDiscrete and Continuous Dynamical Systems - B, 2013
We study the long term dynamics of non-autonomous functional di fferential equations. Namely, we establish existence results on pullback attractors for non-linear neutral functional di erential equations with time varying delays.

Oscillation in neutral partial functional differential equations and inequalities [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 1998
We derive some sufficient conditions for certain classes of ordinary differential inequalities of neutral type with distributed delay not to have eventually positive or negative solutions.

Stability of Nonlinear Neutral Stochastic Functional Differential Equations

open access: yesJournal of Applied Mathematics, 2010
Neutral stochastic functional differential equations (NSFDEs) have recently been studied intensively. The well-known conditions imposed for the existence and uniqueness and exponential stability of the global solution are the local Lipschitz condition ...

Stability of simple periodic solutions of neutral functional differential equations [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2003
We study the stability property of a simple periodic solution of an autonomous neutral functional differential equation (NFDE) of the form $${d\over dt} D(x_t) = f (x_t).$$ A new proof based on local integral manifold theory and the implicit function ...

Critical cases in neutral functional differential equations, arising from hydraulic engineering [PDF]

open access: yesOpuscula Mathematica, 2022
This paper starts from several applications described by initial/boundary value problems for \(1D\) (time and one space variable) hyperbolic partial differential equations whose basic properties and stability of equilibria are studied throughout the same

On the existence of almost periodic solutions of neutral functional differential equations [PDF]

open access: yes, 1998
This paper discusses the existence of almost periodic solutions of neutral functional differential equations. Using a Liapunov function and the Razumikhin's technique, we obtain the existence, uniqueness and stability of almost periodic ...
