Submitted to Computers and Mathematics with Applications DOUBLE INTEGRAL CALCULUS OF VARIATIONS ON TIME SCALES
نویسنده
چکیده
We consider a version of the double integral calculus of variations on time scales, which includes as special cases the classical two-variable calculus of variations and the discrete two-variable calculus of variations. Necessary and sufficient conditions for a local extremum are established, among them an analogue of the Euler–Lagrange equation. AMS (MOS) Subject Classification. 39A0, 49K20.

Symmetric Rogers-Hölder's inequalities on diamond-α calculus
We present symmetric Rogers--Hölder's inequalities on time scales when $frac{1}{p}+frac{1}{q}+frac{1}{r}=0$ and $frac{r}{p}+frac{r}{q}$ is not necessarily equal to $1$ where $p,$ $q$ and $r$ are nonzero real numbers.
متن کاملGeneralizing the variational theory on time scales to include the delta indefinite integral
We prove necessary optimality conditions of Euler–Lagrange type for generalized problems of the calculus of variations on time scales with a Lagrangian depending not only on the independent variable, an unknown function and its delta derivative, but also on a delta indefinite integral that depends on the unknown function. Such kind of variational problems were considered by Euler himself and ha...
متن کاملDouble positive solutions of boundary value problems for p-Laplacian impulsive functional dynamic equations on time scales
This paper is devoted to studying the existence of positive solutions of the boundary value problem for p-Laplacian impulsive functional dynamic equations on time scales. Existence results of at least two positive solutions are established via a fixed point theorem in a cone. c © 2007 Elsevier Ltd. All rights reserved.

This study outlines the local fractional integro-differential equations carried out by the local fractional calculus. The analytical solutions within local fractional Volterra and Abel’s integral equations via the Yang-Laplace transform are discussed. Some illustrative examples will be discussed. The obtained results show the simplicity and efficiency of the present technique with application t...
