Some Dynamic Inequalities via Diamond Integrals for Function of Several Variables

In this paper, Jensen’s inequality and Fubini’s Theorem are extended for the function of several variables via diamond integrals of time scale calculus. These extensions are used to generalize Hardy-type inequalities with general kernels via diamond integrals for the function of several variables. Some Hardy Hilbert and Polya Knop type inequalities are also discussed as special cases. Classical and new inequalities are deduced from the main results using special kernels and particular time scales.

DERIVATIVES BY RATIO PRINCIPLE FOR q-SETS ON THE TIME SCALE CALCULUS

The definitions of derivatives as delta and nabla in time scale theory are kept to follow the notion of the classical derivative. The jump operators are used to transfer the notion from the classical derivative to the derivatives in the time scale theory. The jump operators can be determined by analyst to model phenomena. In this study, the definitions of derivatives in the time scale theory are transferred to ratio of function which has jump operators from [Formula: see text]-deformation. If we use [Formula: see text]-deformation as a subset of real line [Formula: see text], we can have a chance to define a derivative via consulting ratio of two expressions on [Formula: see text]-sets. The applications are performed to produce the new entropy functions by use of the partition function and the derivatives proposed. The concavity and convexity of the proposed entropy functions are examined by use of Taylor expansion with first-order derivative. The entropy functions can catch the rare events in an image. It can be observed that rare events or minor changes in regular pattern of an image can be detected efficiently for different values of [Formula: see text] when compared with the proposed entropies based on [Formula: see text]-sense.

A Survey of Function Analysis and Applied Dynamic Equations on Hybrid Time Scales

As an effective tool to unify discrete and continuous analysis, time scale calculus have been widely applied to study dynamic systems in both theoretical and practical aspects. In addition to such a classical role of unification, the dynamic equations on time scales have their own unique features which the difference and differential equations do not possess and these advantages have been highlighted in describing some complicated dynamical behavior in the hybrid time process. In this review article, we conduct a survey of abstract analysis and applied dynamic equations on hybrid time scales, some recent main results and the related developments on hybrid time scales will be reported and the future research related to this research field is discussed. The results presented in this article can be extended and generalized to study both pure mathematical analysis and real applications such as mathematical physics, biological dynamical models and neural networks, etc.

MULTIPLICATIVE DERIVATIVE AND ITS BASIC PROPERTIES ON TIME SCALES

We define multiplicative derivative and its properties on time scales. Then, we restate many concepts for multiplicative analysis such as derivative, Rolle’s theorem, mean value theorem and increasing decreasing property on time scales. We aim to create important fields of study by carrying this most important issue of multiplicative analysis, which has applications in economics, finance and many other fields, to time scale calculus

The aim of this paper is to synthesize discrete and continuous versions of some dynamic inequalities such as Radon’s Inequality, Bergström’s Inequality, Schlömilch’s Inequality and Rogers-Hölder’s Inequality on time scales in comprehensive form.

Discrete Normal Vector Field Approximation via Time Scale Calculus

The theory of time scales calculus have long been a subject to many researchers from different disciplines. Beside the unification and the extension aspects of the theory, it emerge as a powerful tool for mimetic discretization process. In this study, we present a framework to find normal vector fields of discrete point sets in ℝ3 by using symmetric differential on time scales. A surface parameterized by the tensor product of two time scales can be analogously expressed as the vertex set of non-regular rectangular grids. If the time scales are dense, then the discrete grid structure vanishes. If the time scales are isolated, then the further geometric analysis can be executed by using symmetric dynamic differential. Moreover, we present an algorithmic procedure to determine the symmetric dynamic differential structure on the neighborhood of points in surfaces. Our results indicate that the method we present has good approximation to unit normal vector fields of parameterized surfaces rather than the Delaunay triangulation for some points.
