The results are further generalizations of several previous results. The approach is based on some monotonicity properties of some functions involving the generalized Gamma functions. At the end, some open problems are posed. http://pubs.sciepub.com/tjant/3/4/5/tjant-3-4-5.pdf Gamma function Psi function inequality generalization
