On Fractional and Fractal Derivatives in Relation to the Physics of Fractals

open access: yesRecoletos Multidisciplinary Research Journal, 2013
Fractional and fractal derivatives are both generalizations of the usual derivatives that consider derivatives of non-integer orders. Interest in these generalizations has been triggered by a resurgence of clamor to develop a mathematical tool to ...

New Derivatives on the Fractal Subset of Real-Line [PDF]

open access: yesEntropy, 2016
In this manuscript we introduced the generalized fractional Riemann-Liouville and Caputo like derivative for functions defined on fractal sets. The Gamma, Mittag-Leffler and Beta functions were defined on the fractal sets.

Fractal Geometry of Higher Derivative Gravity [PDF]

open access: yesPhysical Review Letters, 2020
We determine the scaling properties of geometric operators such as lengths, areas, and volumes in models of higher derivative quantum gravity by renormalizing appropriate composite operators. We use these results to deduce the fractal dimensions of such hypersurfaces embedded in a quantum spacetime at very small distances.

Graph Concatenations to Derive Weighted Fractal Networks [PDF]

open access: yesComplexity, 2020
Given an initial weighted graph G0, an integer m>1, and m scaling factors f1,…,fm∈0,1, we define a sequence of weighted graphs Gkk=0∞ iteratively. Provided that Gk−1 is given for k≥1, we let Gk−11,…,Gk−1m be m copies of Gk−1, whose weighted edges have been scaled by f1,…,fm, respectively.

A powerful and simple frequency formula to nonlinear fractal oscillators

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
In this work, a fractal nonlinear oscillator is successfully established by fractal derivative in a fractal space, and its variational principle is obtained by semi-inverse transform method.

Chaos in fractional order financial model with fractal–fractional derivatives

open access: yesPartial Differential Equations in Applied Mathematics, 2023
Recently, a new differential operator which combines fractal differentiation and fractional differentiation with different kernels such as power law, exponential decay, and the Mittag–Leffler function has been introduced.

Application of the Generalized Laplace Homotopy Perturbation Method to the Time-Fractional Black–Scholes Equations Based on the Katugampola Fractional Derivative in Caputo Type

open access: yesComputation, 2021
In the finance market, the Black–Scholes equation is used to model the price change of the underlying fractal transmission system. Moreover, the fractional differential equations recently are accepted by researchers that fractional differential equations

Fractal calculus and its geometrical explanation

open access: yesResults in Physics, 2018
Fractal calculus is very simple but extremely effective to deal with phenomena in hierarchical or porous media. Its operation is almost same with that by the advanced calculus, making it much accessible to all non-mathematicians.

Reproducing kernel Hilbert space method for solving fractal fractional differential equations

open access: yesResults in Physics, 2022
Based on reproducing kernel theory, an analytical approach is considered to construct numerical solutions for some basic fractional ordinary differential equations (FODEs, for short) under fractal fractional derivative with the exponential decay kernel ...

Modeling and analysis of competition model of bank data with fractal-fractional Caputo-Fabrizio operator

open access: yesAlexandria Engineering Journal, 2020
The present paper consider a newly introduced operator known as fractal-fractional where the fractional operator considered is Caputo-Fabrizio. We consider a competition system and propose the field data of banks for 2004–2014 of Indonesia banks of the ...
