TL;DR: In this paper, the authors prove new dynamic Hardy-type inequalities on time scales with two different weighted functions, and apply the results to investigate the oscillation and nonoscillation of a half-linear second order dynamic equation on time scale.
Abstract: In this paper, we will prove some new dynamic Hardy-type inequalities on time scales with two different weighted functions. The study is to determine conditions on which the generalized inequalities hold using some known hypothesis. The main results will be proved by employing Holder’s inequality, Minkowski’s inequality and a chain rule on time scales. As special cases of our results, when the time scale is the real numbers, we will derive some well-known results due to Copson, Bliss, Flett and Bennett by a suitable choice of the weighted functions. We will apply the results to investigate the oscillation and nonoscillation of a half-linear second order dynamic equation on time scales.

TL;DR: In this article, some new dynamic inequalities from which some known dynamic inequalities on time scales, some integral and discrete inequalities due to Hardy, Copson, Chow, Levinson, Pachpatte Yang and Hwang were deduced as special cases.
Abstract: In this paper, we prove some new dynamic inequalities from which some known dynamic inequalities on time scales, some integral and discrete inequalities due to Hardy, Copson, Chow, Levinson, Pachpatte Yang and Hwang will be deduced as special cases. Also, some new corresponding integral and discrete inequalities will be formulated. The results will be proved by employing the chain rule, integration by parts formula, Hölder’s inequality and Jensen’s inequality on time scales.

TL;DR: In this article, the authors proved diamond-alpha dynamic inequalities of Opial type with one and two weight functions on time scales, which contain as special cases improvements of results given in the literature, and these improvements are new even in the important discrete case.

TL;DR: In this article, some new dynamic inequalities on time scales are established, that reduce in the discrete and continuous cases to classical inequalities named after Nemeth and Mohapatra, respectively.
Abstract: Some new dynamic inequalities on time scales are established, that reduce in the discrete and the continuous cases to classical inequalities named after Nemeth and Mohapatra, respectively. The new generalized inequalities resemble intensive classical inequalities known in the literature such as Beesack type inequalities, Copson type inequalities and Hardy–Littlewood type inequalities. The main results will be proved by employing the time scales Holder inequality and the time scales power rules for integrations that have been proved earlier.

TL;DR: In this article, the authors give an affirmative answer to the following question: Is the solvability of some nonlinear dynamic equations on a time scale not only sufficient but in a certain sense also necessary for the validity of some dynamic Hardy-type inequalities with two different weights?
Abstract: In this paper, we give an affirmative answer to the following question: Is the solvability of some nonlinear dynamic equations on a time scale $\mathbb{T}$ not only sufficient but in a certain sense also necessary for the validity of some dynamic Hardy-type inequalities with two different weights? In fact, this answer will give a new characterization of the weights in a weighted Hardy-type inequality on time scales. The results contain the results when $\mathbb{T}=\mathbb{R}$ , $\mathbb{T}=\mathbb{N}$ , and when $\mathbb{T}=q^{\mathbb{N}_{0}}$ as special cases. Some applications are given for illustrations.

TL;DR: In this article, integrals and derivatives of functions on Cantor tartan spaces are defined using F η -calculus, which is used to obtain definitions of the integral and derivative of functions.
Abstract: In this manuscript, integrals and derivatives of functions on Cantor tartan spaces are defined. The generalisation of standard calculus, which is called F η -calculus, is utilised to obtain definitions of the integral and derivative of functions on Cantor tartan spaces of different dimensions. Differential equations involving the new derivatives are solved. Illustrative examples are presented to check the details.
