Abstract In this paper we shall study a functional differential equation of second order with mixed type argument. For this…

AbstractWe study the Ulam–Hyers stability and generalized Ulam–Hyers–Rassias stability for a delay differential equation. Some examples are given. AuthorsD. Otrocol (Tiberiu…

AbstractExistence, uniqueness, data dependence (monotony, continuity, and  differentiability with respect to parameter), and Ulam-Hyers stability results for the solutions of…

Abstract In this paper, we give some general results on the asymptotic relationship between the solutions of a linear differential…

Abstract In this paper we consider a functional integral equation of the form \[ x(t)=g(t,x(t),x(h(t)))+\int_{a}^{t} f(s,x(h(s)))ds+\int_{a}^{b} K(s,x(h(s)))ds, \ \ t…

AbstractIn this paper we present for the solutions of a planar system of differential equations, extremal principle, Nicolescu-type and Butlewski-type…
