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…

AbstractUsing the step method, we study a system of delay differential equations and we prove the existence and uniqueness of…

AbstractIn this paper we study the initial value problem of first order nonlinear differential equations with maxima and discuss the…

AbstractWe consider a mathematical model which describes the quasistatic contact between a viscoelastic body and an obstacle, the so-called foundation.…
