Decreasing Property and Complete Monotonicity of Two Functions Constituted via Three Derivatives of a Function Involving Trigamma Function

Mathematica Slovaca, 2022
Abstract With the aid of convolution theorem of the Laplace transforms, a monotonicity rule for the ratio of two Laplace transforms, Bernstein’s theorem for completely monotonic functions, and other analytic techniques, the author presents decreasing property of a ratio constituted via three derivatives of a sum involving trigamma ...

Estimating the Digamma and Trigamma Functions by Completely Monotonicity Arguments

Applied Mathematics and Computation, 2010
A real valued function \(f\) is completely monotonic on \((0,1)\) if it has derivatives of all orders and for every \(x\in (0,1)\) and \(n\geq 1\), we have \((-1)^nf^{(n)}(x)\geq 0\). Motivated by approximation of the Gamma function and \(n!\), the author considers the function \(F_a:[0,\infty)\to\mathbb{R}\) defined by \[ F_a(x)=\ln\Gamma(x+1)-\left(x+

Completely Monotonic Functions Related to the q-Gamma and the q-Trigamma Functions

Analysis and Applications, 2015
In this paper, two completely monotonic functions involving the q-gamma and the q-trigamma functions where q is a positive real, are introduced and exploited to derive sharp bounds for the q-gamma function in terms of the q-trigamma function. These results, when letting q → 1, are shown to be new. Also, sharp bounds for the q-digamma function in terms
