Advances in Difference Equations , 2009, DOI: 10.1155/2009/484185
Abstract: Our aim in this paper is to investigate some new integral inequalities on time scales, which provide explicit bounds on unknown functions. Our results unify and extend some integral inequalities and their corresponding discrete analogues. The inequalities given here can be used as handy tools to study the properties of certain dynamic equations on time scales.

Bounds of Double Integral Dynamic Inequalities in Two Independent Variables on Time Scales
S. H. Saker
Discrete Dynamics in Nature and Society , 2011, DOI: 10.1155/2011/732164
Abstract: Our aim in this paper is to establish some explicit bounds of the unknown function in a certain class of nonlinear dynamic inequalities in two independent variables on time scales which are unbounded above. These on the one hand generalize and on the other hand furnish a handy tool for the study of qualitative as well as quantitative properties of solutions of partial dynamic equations on time scales. Some examples are considered to demonstrate the applications of the results.

Discrete Dynamics in Nature and Society , 2011, DOI: 10.1155/2011/320794
Abstract: In this paper, we investigate some nonlinear dynamical integral inequalities involving the forward jump operator in two independent variables. These inequalities provide explicit bounds on unknown functions, which can be used as handy tools to study the qualitative properties of solutions of certain partial dynamical systems on time scales pairs. 1. Introduction Theory of dynamical equations on time scales, which goes back to Hilger's landmark paper [1], has received considerable attention in recent years. For example, see the monographs [2, 3] and the references cited therein. Since dynamical integral inequalities usually can be used as handy tools to study the qualitative theory of dynamical equations on time scales, many researchers devoted to the study of different types of integral inequalities on time scales. We refer the readers to [4–19]. To the best of our knowledge, the theory of partial dynamic equations on time scales has received less attention [20–24]. The main purpose of this paper is to investigate several nonlinear integral inequalities in two independent variables on time scale pairs, which can be used to estimate explicit bounds of solutions of certain partial dynamical equations on time scales. Unlike some existing results in the literature (e.g., [12]), the integral inequalities considered in this paper involve the forward jump operator and on a pair of time scales and , which results in difficulties in the estimation on the explicit bounds of unknown functions for and . As an application, we study the qualitative property of certain partial dynamical equations on time scales. Throughout this paper, a knowledge and understanding of time scales and time scale notations is assumed. In what follows, and are two unbounded time scales, and . is the set of right-dense continuous functions on . For an excellent introduction to the calculus on time scales, we refer the reader to monographs [2, 3]. 2. Problem Statements Before establishing the main results of this paper, we first present two useful lemmas as follows. Lemma 2.1. Let , , and . Then, for any , holds, where . Proof. Set . It is not difficult to see that obtains its maximum at and This completes the proof of Lemma 2.1. Lemma 2.2. Let with for . Then implies where and . Proof. Note that , we have that is, By Theorem??6.1 [2, page 255], we get that Lemma 2.2 holds. Consider the following nonlinear integral inequalities in two independent variables on time scales : where , and ( are nonnegative right-dense continuous functions on , ( ) are constants.

Mathematics , 2008, DOI: 10.1080/10236190802213276
Abstract: We establish some nonlinear integral inequalities for functions defined on a time scale. The results extend some previous Gronwall and Bihari type inequalities on time scales. Some examples of time scales for which our results can be applied are provided. An application to the qualitative analysis of a nonlinear dynamic equation is discussed.
Combined dynamic Gruss inequalities on time scales  [PDF]
Moulay Rchid Sidi Ammi,Delfim F. M. Torres
Mathematics , 2008, DOI: 10.1007/s10958-009-9600-2
Abstract: We prove a more general version of the Gruss inequality by using the recent theory of combined dynamic derivatives on time scales and the more general notions of diamond-alpha derivative and integral. For the particular case when alpha = 1, one gets a delta-integral Gruss inequality on time scales; for alpha = 0 a nabla-integral Gruss inequality. If we further restrict ourselves by fixing the time scale to the real (or integer) numbers, then the standard continuous (discrete) inequalities are obtained.
