Neutral functional differential equations of second-order with infinite delays

open access: yesElectronic Journal of Differential Equations, 2010
This work shows the existence of mild solutions to neutral functional differential equations of second-order with infinite delay. The Hausdorff measure of noncompactness and fixed point theorem are used, without assuming compactness on the associated

Spectral Properties and Finite Pole Assignment of Linear Neutral Systems in Banach Spaces

open access: yesAbstract and Applied Analysis, 2010
We will consider a pole assignment problem for a class of linear neutral functional differential equations in Banach spaces. We will think of the neutral system studied as that of involving no time delays and reduce the study of adjoint semigroups and ...

On a neutral functional differential equation in a fading memory space

open access: yesJournal of Differential Equations, 1983
The linear autonomous, neutral system of functional differential equations (*) \((d/dt)(\mu^*x(t)+f(t))=\nu *x(t)+g(t)\) (\(t\geq 0)\), \(x(t)=\phi (t)\) (\(t\leq 0)\), in a fading memory space is studied. Here \(\mu\) and \(\nu\) are matrix-valued measures supported on [0,\(\infty)\), finite with respect to a weight function, and f,g, and \(\phi\) are

Explicit stability conditions for neutral type vector functional differential equations. A survey [PDF]

open access: yesSurveys in Mathematics and its Applications, 2014
This paper is a survey of the recent results of the author on the stability of linear and nonlinear neutral type functional differential equations. Mainly, vector equations are considered. In particular, equations whose nonlinearities are causal mappings
