Summary: The fractional oscillation equation is obtained from the classical equation for linear oscillations by replacing the second-order time derivative by a fractional derivative of order \(\alpha\) with \(1<\alpha<2\). Using the Laplace transform, it is shown that the fundamental solutions can be expressed in terms of Mittag-Leffler functions, and exhibit a finite number of damped oscillations with an algebraic decay. For completeness the authors discuss both the cases \(0<\alpha<1\) (fractional relaxation) and \(2<\alpha\leq 3\) (growing oscillations), showing the key role of the Mittag-Leffler functions.
