Abstract
In this paper, we prove the monotonicity property of the ratios of Mittag-Leffler functions. As applications, new functional inequalities (such as Turán type inequalities) for the Mittag-Leffler function are obtained. Moreover, geometrical convexity and log-concavity properties for some classes of functions related to the Mittag-Leffler function are researched. Furthermore, new formulas and inequalities for some integrals involving the Mittag-Leffler functions are established.
