FRACTIONAL DERIVATIVE AS FRACTIONAL POWER OF DERIVATIVE [PDF]

open access: greenInternational Journal of Mathematics, 2007
Definitions of fractional derivatives as fractional powers of derivative operators are suggested. The Taylor series and Fourier series are used to define fractional power of selfadjoint derivative operator. The Fourier integrals and Weyl quantization procedure are applied to derive the definition of fractional derivative operator.

The Fractional Orthogonal Derivative [PDF]

open access: yesMathematics, 2015
This paper builds on the notion of the so-called orthogonal derivative, where an n-th order derivative is approximated by an integral involving an orthogonal polynomial of degree n.

On multifractality and fractional derivatives [PDF]

open access: greenJournal of Statistical Physics, 2002
It is shown phenomenologically that the fractional derivative $ =D^ u$ of order $ $ of a multifractal function has a power-law tail $\propto | | ^{-p_\star}$ in its cumulative probability, for a suitable range of $ $'s. The exponent is determined by the condition $ _{p_\star} = p_\star$, where $ _p$ is the exponent of the structure function of

Fractional Derivatives and Projectile Motion [PDF]

open access: yesAxioms, 2021
Projectile motion is studied using fractional calculus. Specifically, a newly defined fractional derivative (the Leibniz L-derivative) and its successor (Λ-fractional derivative) are used to describe the motion of the projectile.

Fractional Derivatives as Inverses [PDF]

open access: bronzeCanadian Journal of Mathematics, 1989
We write formally (C, p) indicating that the integral is summable (C, p), i.e.,if this limit exists. We note here that all integrals over a finite range are taken in the Lebesgue sense, and all inversions of such iterated integrals are justifiable by Fubini's Theorem.

Application of Newton’s polynomial interpolation scheme for variable order fractional derivative with power-law kernel [PDF]

open access: yesScientific Reports
This paper, offers a new method for simulating variable-order fractional differential operators with numerous types of fractional derivatives, such as the Caputo derivative, the Caputo–Fabrizio derivative, the Atangana–Baleanu fractal and fractional ...

Calculus of variations with fractional derivatives and fractional integrals

open access: bronzeApplied Mathematics Letters, 2009
We prove Euler-Lagrange fractional equations and sufficient optimality conditions for problems of the calculus of variations with functionals containing both fractional derivatives and fractional integrals in the sense of Riemann-Liouville.

On Λ-Fractional Viscoelastic Models

open access: yesAxioms, 2021
Λ-Fractional Derivative (Λ-FD) is a new groundbreaking Fractional Derivative (FD) introduced recently in mechanics. This derivative, along with Λ-Transform (Λ-T), provides a reliable alternative to fractional differential equations’ current solving.
