Implementation of quantum and classical discrete fractional Fourier transforms [PDF]

open access: goldNature Communications, 2016
Fourier analysis has become a standard tool in contemporary science. Here, Weimann et al. report classical and quantum optical realizations of the discrete fractional Fourier transform, a generalization of the Fourier transform, with potential ...

Abelian and Tauberian results for the fractional Fourier cosine (sine) transform

open access: goldAIMS Mathematics
In this paper, we presented Tauberian type results that intricately link the quasi-asymptotic behavior of both even and odd distributions to the corresponding asymptotic properties of their fractional Fourier cosine and sine transforms.

Space-Time Fractional Reaction-Diffusion Equations Associated with a Generalized Riemann–Liouville Fractional Derivative [PDF]

open access: yesAxioms, 2014
This paper deals with the investigation of the computational solutions of a unified fractional reaction-diffusion equation, which is obtained from the standard diffusion equation by replacing the time derivative of first order by the generalized Riemann ...

Fractional fourier transforms of hypercomplex signals [PDF]

open access: yesSignal, Image and Video Processing, 2012
An overview is given to a new approach for obtaining generalized Fourier transforms in the context of hypercomplex analysis (or Clifford analysis). These transforms are applicable to higher-dimensional signals with several components and are different ...

Unsteady two dimensional flow of non-newtönian fractional Casson fluid for an edge with heated boundaries [PDF]

open access: yesScientific Reports
This study explores the transient flow and thermal behavior of incompressible non-Newtonian fluids, with a particular emphasis on Casson and fractional Casson models, which are widely applied in blood flow, lubricants, and polymer processing.

Fractional Fourier transforms of vortex Hermite-cosh-Gaussian beams

open access: yesResults in Optics, 2021
In this paper, we investigate the propagation properties of a vortex Hermite-cosh-Gaussian beam (vHChGB) passing through a fractional Fourier transform (FRFT) optical system.

On the Fractional Derivative Duality in Some Transforms

open access: yesMathematics, 2023
Duality is one of the most interesting properties of the Laplace and Fourier transforms associated with the integer-order derivative. Here, we will generalize it for fractional derivatives and extend the results to the Mellin, Z and discrete-time Fourier
