Abstract Since its inception in 1894, the Monthly has printed 50 articles on the Γ function or Stirling's asymptotic formula, including the magisterial 1959 paper by Phillip J. Davis, which won the 1963 Chauvenet prize, and the eye-opening 2000 paper by the Fields medalist Manjul Bhargava. In this article, we look back and comment on what has been said, and why, and try to guess what will be said about the Γ function in future Monthly issues.11 It is a safe bet that there will be more proofs of…

Stirling’s Original Asymptotic Series from a Formula Like One of Binet’s and its Evaluation by Sequence Acceleration

Abstract We give an apparently new proof of Stirling’s original asymptotic formula for the behavior of for large z. Stirling’s original formula is not the formula widely known as “Stirling’s…

Regularized Integral Representations of the Reciprocal Γ Function

Applications of the Gamma function are ubiquitous in fractional calculus and the special function 7 theory. It has numerous interesting properties summarized in [1]. It is indispensable in the theory…

Computation of matrix gamma function

This research article proposes a fourth technique based on the reciprocal gamma function that is shown to be competitive with the other three methods in terms of accuracy, with the advantage of being rich in matrix multiplications.

A new computational framework for evaluation of the gamma function Γ(z) over the complex plane is developed. The algorithm is based on interpolation by rational functions, and generalizes the…

Arbitrary-precision computation of the gamma function

The best methods available for computing the gamma function Γ(z) in arbitrary-precision arithmetic with rigorous error bounds are discussed and some new formulas, estimates, bounds and algorithmic improvements are presented.

Three Theorems of Menelaus

Three theorems due to Menelaus of Alexandria (1st–2nd century A.D.) that concern spherical triangles are presented and his methods of proof more widely known.

Weighted Prime Powers Truncation of the Asymptotic Expansion for the Logarithmic Integral: Properties and Applications

ABSTRACT. Letting the truncation point for the Logarithmic Integral’s asymptotic expansion be the variable to solve for, though not to be minimized as with the usual Stieltjes truncation. Instead…

The Euler characteristic of Out($F_n$)

. We prove that the rational Euler characteristic of Out( F n ) is always negative and its asymptotic growth rate is Γ( n − 32 ) / √ 2 π log 2 n . This settles a 1987 conjecture of J. Smillie and the…

Asymptotics of some generalized Mathieu series

We establish asymptotic estimates of Mathieu-type series defined by sequences with power-logarithmic or factorial behavior. By taking the Mellin transform, the problem is mapped to the singular…

The method is adapted to obtain Stirling's series for the logarithm of the gamma function and it is shown that the constants obtained are the best ones possible, i.e., they cannot be improved by any method whatsoever.
