The concept of inequalities in time scales has attracted the attention of mathematicians for a quarter century. And these studies have inspired the solution of many problems in the branches of physics, biology, mechanics and economics etc. In this article, new principles of non-linear integral inequalities are presented in time scales via diamond-

For a quarter century, the theory of time scales has played an important role in the representation of differential calculus and integral inequalities. The concept of time scales was introduced by Stefan Hilger in 1988 [1]. Later, this theory was studied by many authors. They have demonstrated various aspects of integral inequalities [2,3,4,5,6,7,8,9,10,11,12,13]. Dynamic equations and inequalities have many applications to quantum mechanics, phsical problems, wave equations, heat transfer and economic problems [26, 27, 28, 29]. For example; Aly R. Seadawy et al. have done a lot of research on the applications of dynamic equations in physics. As a result of these studies, they achieved good results [30]. The most important examples of time scale studies are differential calculus and inequalities [12]. Wong et al. [6, 7] expressed some time scale integral inequalities. Yang [13] obtained a generalization of the ⋄_{α}-integral Hölder's inequality in time scales. Recently, Li Yin and Feng Qi [24] have introduced some non-linear integral inequalities under certain conditions.

Our aim of this article is to demonstrate new principles of non-linear integral inequalities in time scales via the ∇-integral and the ⋄_{α}-integral.

Now, let us briefly give information about time scales and give the necessary definitions and notations for our article. For more details, we refer the reader to the articles [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25].

If we use Cauchy's Mean Value Theorem together with the condition given in the theorem, we get the following.

If we use Cauchy's Mean Value Theorem consecutively in (7), we obtain

Integral inequalities and dynamic equations are the cornerstones of both time scales and harmonic analysis. Mathematicians proved many integral inequalities on time scales [4,5,6,7,8,9]. And they also showed generalized forms of these inequalities [10, 11, 13, 25]. Time scales theory has also been of interest in different sciences. For example, quantum mechanics, wave equations, physical problems, heat transfer, electrical engineering and economics [26,27,28,29,30]. In this article, we proved non-linear integral inequalities in time scales via the ∇-integral and the ⋄_{a}-integral. We think that the multidimensional and multivariate cases of the inequalities proved in this article are also worth examining.
