Boundary value problems for functional-differential equations with nonlinear boundary conditions

Panagiotis Ch. Tsamatos (1998)

Archivum Mathematicum

This paper is concerned with the existence of solutions for some class of functional integrodifferential equations via Leray-Schauder Alternative. These equations arised in the study of second order boundary value problems for functional differential equations with nonlinear boundary conditions.

Boundary value problems for systems of functional differential equations

Tadeusz Jankowski (2002)

Applications of Mathematics

Algorithms for finding an approximate solution of boundary value problems for systems of functional ordinary differential equations are studied. Sufficient conditions for consistency and convergence of these methods are given. In the last section, a construction of methods of arbitrary order is presented.

Bounded oscillation of nonlinear neutral differential equations of arbitrary order

Yeter Ş. Yilmaz, Ağacik Zafer (2001)

Czechoslovak Mathematical Journal

The paper is concerned with oscillation properties of $n$ -th order neutral differential equations of the form ${[x (t) + c x (τ (t))]}^{(n)} + q (t) f (x (σ (t))) = 0, t \geq t_{0} > 0,$ where $c$ is a real number with $| c | \neq 1$ , $q \in C ([t_{0}, \infty), ℝ)$ , $f \in C (ℝ, ℝ)$ , $τ, σ \in C ([t_{0}, \infty), ℝ_{+})$ with $τ (t) < t$ and ${lim}_{t \to \infty} τ (t) = {lim}_{t \to \infty} σ (t) = \infty$ . Sufficient conditions are established for the existence of positive solutions and for oscillation of bounded solutions of the above equation. Combination of these conditions provides necessary and sufficient conditions for oscillation of bounded solutions of the equation. Furthermore, the results are generalized to equations in which...

Boundedness and stability in third order nonlinear differential equations with multiple deviating arguments

Moussadek Remili, Lynda D. Oudjedi (2016)

Archivum Mathematicum

In this paper, we establish some new sufficient conditions which guarantee the stability and boundedness of solutions of certain nonlinear and non autonomous differential equations of third order with delay. By defining appropriate Lyapunov function, we obtain some new results on the subject. By this work, we extend and improve some stability and boundedness results in the literature.
