Fuzzy fractional neutral equation

2020 IEEE 6th International Conference on Optimization and Applications (ICOA), 2020
This paper is devoted to a class of nonlinear fuzzy neutral functional differential equations. Specifically, existence and uniqueness of fuzzy solution for the nonlinear fuzzy neutral functional differential equation\begin{equation*} {}_{gH}D^{\gamma}[x(t)-gf(t,\ x_{t})]=Ax(t)+g(t,\ x_{t}). \end{equation*} where $A$ is an operator from $E^{1}$ into

Stability in neutral equations

Nonlinear Analysis: Theory, Methods & Applications, 1977
Abstract : Coupled systems of differential-difference and ordinary difference equations occur in various applications including the theory of transmission lines (1) and gas dynamics (2). Stability of linear systems has been discussed by Brayton (1) using Laplace transform and the problem of absolute stability by Rasvan (12) using the frequency domain ...

Oscillations of Second Order Neutral Equations

Canadian Journal of Mathematics, 1988
Consider the second order neutral differential equation1where the coefficients p and q and the deviating arguments τ and σ are real numbers. The characteristic equation of Eq. (1) is2The main result in this paper is the following necessary and sufficient condition for all solutions of Eq. (1) to oscillate.THEOREM.

Neutral Differential Equations

2012
Chapter 6 deals with nonoscillation and oscillation properties of scalar linear neutral differential equations. There are two kinds of neutral equations, one of them can be integrated leading to a term with a concentrated delay and an integral term; the second type which is considered in this chapter has a derivative involved both without a delay and ...

Neutral Mixed Type Functional Differential Equations

Journal of Dynamics and Differential Equations, 2015
The 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 ...
