Fractional calculus was introduced in one of Niels Henrik Abel's early papers [4] where all the elements can be found: the idea of fractional-order integration and differentiation, the mutually inverse relationship between them, the understanding that fractional-order differentiation and integration can be considered as the same generalized ...
It covers research on fractional calculus, special functions, integral transforms, and some closely related areas of applied analysis. The journal is abstracted and indexed in Science Citation Index Expanded, Scopus, Current Contents/Physical, Chemical and Earth Sciences, Zentralblatt MATH, and Mathematical Reviews.

In fractional calculus, these formulae can be used to construct a differintegral, allowing one to differentiate or integrate a fractional number of times. Differentiating a fractional number of times can be accomplished by fractional integration, then differentiating the result.
Supposing that y(t) be continuous and fractal differentiable on (a, b) with order β, several definitions of a fractal–fractional derivative of y(t) hold with order α in the Riemann–Liouville sense: [4] Having power law type kernel:
Japanese mathematics (和算, wasan) denotes a distinct kind of mathematics which was developed in Japan during the Edo period (1603–1867). The term wasan , from wa ("Japanese") and san ("calculation"), was coined in the 1870s [ 1 ] and employed to distinguish native Japanese mathematical theory from Western mathematics (洋算 yōsan ).
If the differ integral is initialized properly, then the hoped-for composition law holds. The problem is that in differentiation, information is lost, as with C in the first equation. However, in fractional calculus, given that the operator has been fractionalized and is thus continuous, an entire complementary function is needed.
In mathematics, the Grünwald–Letnikov derivative is a basic extension of the derivative in fractional calculus that allows one to take the derivative a non-integer number of times. It was introduced by Anton Karl Grünwald (1838–1920) from Prague , in 1867, and by Aleksey Vasilievich Letnikov (1837–1888) in Moscow in 1868.
