“…for all t I. Lemma 6 (see [5]). Let C(R + ,R + ) be a increasing function, u,a,f C([t 0 ,T),R + ), a (t) be a increasing function, and a C 1 ([t 0 ,T), [t 0 ,T)) be nondecreasing with a(t) ≤ t on [t 0 ,T) where T (0,∞) is a constant.…”
In this article, we discuss some generalized retarded nonlinear integral inequalities, which not only include nonlinear compound function of unknown function but also include retard items, and give upper bound estimation of the unknown function by integral inequality technique. This estimation can be used as tool in the study of differential equations with the initial conditions. 2000 MSC: 26D10; 26D15; 26D20; 34A12; 34A40.

Some nonlinear discrete weakly singular inequalities, which generalize some known results are discussed. Under suitable parameters, prior bounds on solutions to nonlinear Volterra-type difference equations are obtained. Two examples are presented to show the applications of our results in boundedness and uniqueness of solutions of difference equations, respectively. MSC: 34A34; 45J05
“…During the past few years there have been a number of papers written on discrete versions of Gronwall-Bellman-type inequalities. For example, see [1][2][3][4][5][6][7][8][9][10][11][12][13]. Found in [6], the unknown function u in the fundamental form of sumdifference inequality …”
-In this paper, some new discrete nonlinear inequalities with two variables are established and explicit bounds on the unknown function are derived. These inequalities generalize former results and can be used as handy tools to study the qualitative as well as the quantitative properties of certain partial difference equations. Example of applying these inequalities to derive the properties of boundary Value problems for difference equations is also given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
