αβ−STATISTICAL CONVERGENCE ON TIME SCALES [PDF]

, 2020
In this paper, we introduce the concepts of $\alpha\beta-$statistical convergence and strong $\alpha \beta-$Ces\`{a}ro summability of delta measurable functions on anarbitrary time scale.

Generalized weighted Ostrowski and Ostrowski-Gruss type inequalities on time scales via a parameter function [PDF]

, 2017
We prove generalized weighted Ostrowski and Ostrowski–Gr ¨uss type inequalities on time scales via a parameter function. In particular, our result extends a result of Dragomir and Barnett.

Rofe-Beketov formula for symplectic systems

Advances in Differential Equations, 2012
We establish the Rofe-Beketov formula for symplectic systems on time scales. This result generalizes the well-known d’Alembert formula (or the Reduction of Order Theorem) and the Rofe-Beketov formula published for the second order Sturm-Liouville ...

A unified approach to the calculus of variations on time scales

, 2010
In this work we propose a new and more general approach to the calculus of variations on time scales that allows to obtain, as particular cases, both delta and nabla results. More precisely, we pose the problem of minimizing or maximizing the composition

Variable order Mittag-Leffler fractional operators on isolated time scales and application to the calculus of variations

, 2018
We introduce new fractional operators of variable order on isolated time scales with Mittag-Leffler kernels. This allows a general formulation of a class of fractional variational problems involving variable-order difference operators.

Progranulin plasma levels predict the presence of GRN mutations in asymptomatic subjects and do not correlate with brain atrophy: results from the GENFI study. [PDF]

, 2018
We investigated whether progranulin plasma levels are predictors of the presence of progranulin gene (GRN) null mutations or of the development of symptoms in asymptomatic at risk members participating in the Genetic Frontotemporal Dementia Initiative ...

Inequalities and majorisations for the Riemann-Stieltjes integral on time scales

, 2010
We prove dynamic inequalities of majorisation type for functions on time scales. The results are obtained using the notion of Riemann-Stieltjes delta integral and give a generalization of [App. Math. Let. 22 (2009), no.

The contingent epiderivative and the calculus of variations on time scales

, 2010
The calculus of variations on time scales is considered. We propose a new approach to the subject that consists in applying a differentiation tool called the contingent epiderivative.
