The Mittag-Leffler function

Mostly known as the man because of whom mathematicians are not entitled to the Nobel prize, the Swedish mathematician Gösta Mittag-Leffler, the man who – the legend has it – had an affair with Nobel’s wife, is little known for his namesake function (for the record, Nobel never had a wife). The Mittag-Leffler function arises in several applications in physics and mathematics, chiefly in the solution of fractional-order differential equations – a well-studied special type of integrodifferential equations [1]. The function is given in the form of an infinite convergent series. A straightforward way to compute then would be to sum up the terms of this series until, eventually, the sum does not change. This, however, would be neither fast not accurate. In this article we are discussing about numerical methods for the computation of the Mittag-Leffler function. Continue reading →
