Abstract

In the article we present necessary and sufficient conditions for a function involving the logarithm of the gamma function to be completely monotonic and apply these results to bound the gamma function Γ(x)\Gamma(x), the nn-th harmonic number k=1n1k\sum_{k=1}^n\frac1k, and the factorial n!n!.
