Some inequalities involving ratios and products of the gamma function
Le Matematiche, 2013 In this paper, we establish some generalized inequalities for the gamma function using the properties of logarithmically convex/concave functions.

On some properties of digamma and polygamma functions
Journal of Mathematical Analysis and Applications, 2007 The author proves some interesting inequalities involving the logarithmic derivative of the gamma function \(\psi(x)=\frac{\Gamma^{\prime}(x)}{\Gamma(x)}\), and its derivatives \(\psi_{n}(x)=\psi^{(n)}(x),\;n=1,2,3,\ldots\), known as polygamma functions.

Functional relations involving generalized H-function
Le Matematiche, 1998 A number of papers have appeared in literature in which certain functional relations associated with hypergeometric functions and Digamma function ψ(z) are derived. In order to unify and extend the existing results due to Kalla [7].
