Abstract:A logarithmically completely monotonic function is completely monotonic. The function 1 − ln x + 1x ln Γ (x + 1) is strictly completely monotonic on (0, ∞). The function x √ Γ (x + 1)/x is strictly logarithmically completely monotonic on (0, ∞).

Abstract. In this paper, the logarithmically complete monotonicity results of the functions [Γ(1 + x)] y /Γ(1 + xy) and Γ(1 + y)[Γ(1 + x)] y /Γ(1 + xy) are established.

In the paper, the authors present the Schur-convexity of the absolute of the logarithm of the Catalan-Qi function and prove the logarithmically complete monotonicity of the Catalan-Qi function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
