Geometric interpretation of the fractional derivative. (English) Zbl 0907.26005

Several definitions of fractional calculus, integration and differentiation of arbitrary order, have been given by various authors. The present author considers the definitions given by Nishimoto, Osler, and the so-called Riemann-Liouville definition. He gives a geometric interpretation of the argument and module of fractional derivative of order \(\alpha\in]0, 1]\).
