Fractional calculus is a branch of mathematical analysis that studies the several different possibilities of defining real number powers or complex number powers of ...
The definitions of fractional derivatives given by Liouville, Fourier, and Grunwald and Letnikov coincide. [1] ... Fractional Calculus and Applied Analysis. 5 (4): ...
In mathematics, the Riemann–Liouville integral associates with a real function: another function I α f of the same kind for each value of the parameter α > 0.The integral is a manner of generalization of the repeated antiderivative of f in the sense that for positive integer values of α, I α f is an iterated antiderivative of f of order α.
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.
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.
In mathematics, the Weyl integral (named after Hermann Weyl) is an operator defined, as an example of fractional calculus, on functions f on the unit circle having integral 0 and a Fourier series. In other words there is a Fourier series for f of the form = with a 0 = 0
The truth is that all these definitions can be true. In order to fully capture the essence of 2024, and to honor the power of photography, we needed to consider multiple categories and forms of ...
