Approximate controllability of quasilinear functional differential equations

Electronic Journal of Differential Equations, 2019
In this article, we study the approximate controllability for quasilinear differential equations with deviating arguments in a Hilbert space. We establish sufficient conditions for the existence of a mild solution. We also obtain sufficient conditions

Special solutions of neutral functional differential equations

Journal of Inequalities and Applications, 2001
For a system of nonlinear neutral functional differential equations we prove the existence of an -parameter family of "special solutions" which characterize the asymptotic behavior of all solutions at infinity.

Uniform Stability and Boundedness of a Kind of Third Order Delay Differential Equations

Bulletin of Computational Applied Mathematics, 2014
By constructing a Lyapunov functional, we obtain some sufficient conditions which guarantee the stability and boundedness of solutions for some nonlinear differential equations of third order with delay.

Bogdanov-Takens bifurcation for neutral functional differential equations

Electronic Journal of Differential Equations, 2013
In this article, we consider a class of neutral functional differential equations (NFDEs). First, some feasible assumptions and algorithms are given for the determination of Bogdanov-Takens (B-T) singularity.
