Construction of the Digamma Function by Derivative Definition

, 2008
The Digamma and Polygamma functions are important tools in mathematical physics, not only for its many properties but also for the applications in statistical mechanics and stellar evolution. In many textbooks is found its develop almost by the same procedure. In this paper expressions for the Digamma and Polygamma functions, in terms of hypergeometric

Complete monotonicity of a function involving derivatives of the Barnes G-function

Journal of Inequalities and Applications
In this manuscript, we present the complete monotonicity of functions defined in terms of the poly-double gamma function ψ 2 ( n ) ( x ) = ( − 1 ) n + 1 n ! ∑ k = 0 ∞ ( 1 + k ) ( x + k ) n + 1 , x > 0 , n ≥ 2 . $$\begin{aligned} \psi _{2}^{(n)}(x) = (-1)^
