Some monotonicity properties and inequalities for the generalized digamma and polygamma functions.

Several monotonicity and concavity results related to the generalized digamma and polygamma functions are presented. This extends and generalizes the main results of Qi and Guo and others.

Turán type inequalities for generalized Mittag-Leffler function.

In this paper, we show several Turán type inequalities for a generalized Mittag-Leffler function with four parameters via the [Formula: see text]-gamma function.
