Abstract

In this paper, we discuss a class of retarded nonlinear integral inequalities and give an upper bound estimation of an unknown function by the integral inequality technique. This estimation can be used as a tool in the study of differential-integral equations with the initial conditions.MSC:26D10, 26D15, 26D20, 34A12, 34A40.

Highlights

  • Gronwall-Bellman inequalities [, ] can be used as important tools in the study of existence, uniqueness, boundedness, stability, and other qualitative properties of solutions of differential equations, integral equations, and integral-differential equations

  • There can be found a lot of generalizations of Gronwall-Bellman inequalities in various cases from literature (e.g., [ – ])

  • Lemma (Abdeldaim and Yakout [ ]) We assume that u(t) and f (t) are nonnegative realvalued continuous functions defined on I = [, ∞) and they satisfy the inequality t
