On the Variable Order Fractional Calculus Characterization for the Hidden Variable Fractal Interpolation Function

open access: yesFractal and Fractional, 2022
In this study, the variable order fractional calculus of the hidden variable fractal interpolation function is explored. It extends the constant order fractional calculus to the case of variable order. The Riemann–Liouville and the Weyl–Marchaud variable

A Fractional Calculus of Variations for Multiple Integrals with Application to Vibrating String [PDF]

open access: yes, 2010
We introduce a fractional theory of the calculus of variations for multiple integrals. Our approach uses the recent notions of Riemann-Liouville fractional derivatives and integrals in the sense of Jumarie. Main results provide fractional versions of the

Foundations of generalized Prabhakar-Hilfer fractional calculus with applications

open access: yesCubo, 2021
Here we introduce the generalized Prabhakar fractional calculus and we also combine it with the generalized Hilfer calculus. We prove that the generalized left and right side Prabhakar fractional integrals preserve continuity and we find tight upper ...
