Approximation for the gamma function via the tri-gamma function
In this paper, we present a new sharp approximation for the gamma function via the tri-gamma function. This approximation is fast in comparison with the recently discovered asymptotic series. We also establish the inequalities related to this approximation. Finally, some numerical computations are provided for demonstrating the superiority of our approximation.
متن کاملAn accurate approximation formula for gamma function
In this paper, we present a very accurate approximation for the gamma function: [Formula: see text] as [Formula: see text], and we prove that the function [Formula: see text] is strictly decreasing and convex from [Formula: see text] onto [Formula: see text], where [Formula: see text].
متن کاملInequalities for the Gamma Function
We prove the following two theorems: (i) Let Mr(a, b) be the rth power mean of a and b. The inequality Mr(Γ(x), Γ(1/x)) ≥ 1 holds for all x ∈ (0,∞) if and only if r ≥ 1/C − π2/(6C2), where C denotes Euler’s constant. This refines results established by W. Gautschi (1974) and the author (1997). (ii) The inequalities xα(x−1)−C < Γ(x) < xβ(x−1)−C (∗) are valid for all x ∈ (0, 1) if and only if α ≤...

A necessary and sufficient condition in terms of lower cut sets are given for the insertion of a $gamma-$continuous function between two comparable real-valued functions.
متن کاملThe Gamma function revisited
We find several new representations of the Gamma function (and related functions such as R(z) = Γ(z)/Γ(−z), Binet’s function μ(z), and ln Γ(z)) as integrals and partial-fraction-like expansions. We also present convergent and/or better versions of Stirling’s formula, fully general reflection and shift formulas for the Gamma function, new continued fractions and new error estimates (such as unde...
