Stability Analysis of Nonlinear Neutral Functional Differential Equations [PDF]
SIAM Journal on Control and Optimization, 2017 Employing a system transformation, the comparison principle and the spectral properties of Metzler matrices, the authors derive some new explicit criteria for the exponential stability of general nonlinear neutral functional differential equations. The results so obtained are both delay-dependent and delay-independent criteria.

On the existence of periodic solutions for a kind of high-order neutral functional differential equation [PDF]
Journal of Mathematical Analysis and Applications, 2007 By using the coincidence degree theory of Mawhin, we study a kind of high-order neutral functional differential equation with distributed delay as follows:(x(t)−cx(t−σ))(n)+f(x(t))x′(t)+g(∫−r0x(t+s)dα(s))=p(t).

Neutral Mixed Type Functional Differential Equations
Journal of Dynamics and Differential Equations, 2015The authors consider implicitly defined equations of mixed type which arose from examining electrical signaling in cardiac tissue and nerve conduction models. They are studying travelling wave solutions \((\phi,c)\) with \(\phi\) waveform and wave speed \(c\) which satisfy the following equation: \[ \sum\limits^N_{j=1}B_j(\xi)\left[-c\phi'(\xi+r_j)+f ...
