Mathematical Model of Fractional Duffing Oscillator with Variable Memory

open access: yesMathematics, 2020
The article investigates a mathematical model of the Duffing oscillator with a variable fractional order derivative of the Riemann–Liouville type. The study of the model is carried out using a numerical scheme based on the approximation of the fractional

Fractional generalizations of filtering problems and their associated fractional Zakai equations [PDF]

open access: yes, 2014
In this paper we discuss fractional generalizations of the filtering problem. The ”fractional” nature comes from time-changed state or observation processes, basic ingredients of the filtering problem. The mathematical feature of the fractional filtering

Cauchy problems for fractional differential equations with Riemann–Liouville fractional derivatives

open access: yesJournal of Functional Analysis, 2012
AbstractIn this paper, we are concerned with Cauchy problems of fractional differential equations with Riemann–Liouville fractional derivatives in infinite-dimensional Banach spaces. We introduce the notion of fractional resolvent, obtain some its properties, and present a generation theorem for exponentially bounded fractional resolvents. Moreover, we

Extended Riemann-Liouville type fractional derivative operator with applications

open access: yesOpen Mathematics, 2017
Abstract The main purpose of this paper is to introduce a class of new extended forms of the beta function, Gauss hypergeometric function and Appell-Lauricella hypergeometric functions by means of the modified Bessel function of the third kind. Some typical generating relations for these extended hypergeometric functions are obtained by defining the ...

A new construction of a fractional derivative mask for image edge analysis based on Riemann-Liouville fractional derivative

open access: yes, 2016
We present a new way of constructing a fractional-based convolution mask with an application to image edge analysis. The mask was constructed based on the Riemann-Liouville fractional derivative which is a special form of the Srivastava-Owa operator ...
