Existence and Uniqueness of solutions for fractional neutral stochastic delay differential equations

Xi'an Gongcheng Daxue xuebao, 2022
Using the idea of step method, we discassed the existence and uniqueness of solutions of fractional neutral stochastic delay differential equations in the interval ［0,τ］,［τ,2τ］,…,［(n-1)τ,nτ］. Combining Picard iterative method and integral operator theory,

On Neutral Functional–Differential Equations with Proportional Delays

Journal of Mathematical Analysis and Applications, 1997
The paper deals with the well-posedness of the initial value problem for the neutral functional-differential equation \[ y'(t)= ay(t)+ \sum_{i=1}^\infty b_iy(q_it)+ \sum_{i=1}^\infty cy'(p_it), \qquad t>0, \quad y(0)=y_0 \] and the asymptotic behaviour of its solutions.

Oscillation of Solutions to Nonlinear Neutral Delay Differential Equations [PDF]

Journal of Applied Analysis, 2002
The authors consider nonlinear neutral delay differential equations with variable coefficients. Some new sufficient conditions for the oscillation of all solutions are obtained. The results extend and improve some of the well known results in the literature. Some examples are considered to illustrate the main results. The neutral logistic equation with

An Oscillation Test for Solutions of Second-Order Neutral Differential Equations of Mixed Type

Mathematics, 2021
It is easy to notice the great recent development in the oscillation theory of neutral differential equations. The primary aim of this work is to extend this development to neutral differential equations of mixed type (including both delay and advanced ...
