This paper has two parts. The first part surveys Euler's work on the constant gamma=0.57721... bearing his name, together with some of his related work on the gamma function, values of the zeta function and divergent series. The second part describes various mathematical developments involving Euler's constant, as well as another constant, the Euler-Gompertz constant. These developments include connections with arithmetic functions and the Riemann hypothesis, and with sieve methods, random…

Fractional parts and their relations to the values of the Riemann zeta function
A well-known result, due to Dirichlet and later generalized by de la Vallée–Poussin, expresses a relationship between the sum of fractional parts and the Euler–Mascheroni constant. In this paper, we
On certain alternating series involving zeta and multiple zeta values
In this article, we consider various generalizations of Euler's famous relation \[ \gamma = \sum_{n\geq 2} (-1)^n \frac{\zeta(n)}{n} \] linking Euler's constant $\gamma$ to special values of the
Euler's factorial series, Hardy integral, and continued fractions
. We study p -adic Euler’s series E p ( t ) = P ∞ k =0 k ! t k at a point p a , a ∈ Z ≥ 1 , and use Pad´e approximations to prove a lower bound for the p -adic absolute value of the expression cE p (
A one parameter generalization of Euler’s constant γ from [Numer. Algorithms 46(2) (2007) 141–151] is investigated, and additional expressions for γ are derived. Included are forms involving the
Another Alternating Analogue of Euler’s Constant
Abstract In 2005 Jonathan Sondow found several interesting analogies between Euler’s constant γ and revealing that the latter may be regarded as the alternating analogue of Euler’s constant. In this
From Euler's play with infinite series to the anomalous magnetic moment
During a first St. Petersburg period Leonhard Euler, in his early twenties, became interested in the Basel problem: summing the series of inverse squares (posed by Pietro Mengoli in mid 17th
Euler ’ s Constant : New Insights by Means of Minus One Factorial
The great object of this paper is to furnish, in a concise and plain manner, new insights into that mysterious constant whose arithmetic nature was shrouded in obscurity for over 250 years, the


Euler’s constant, q-logarithms, and formulas of Ramanujan and Gosper
The aim of the paper is to relate computational and arithmetic questions about Euler’s constant γ with properties of the values of the q-logarithm function, with natural choice of~q. By these means,
Euler's Constant to 1271 Places
The value of Euler's or Mascheroni's constant Pi = lim"'. (1 + 2 + + (1/n) inn) has now been determined to 1271 decimal places, thus extending the previously known value of 328 places. A calculation
The Theory of the Riemann Zeta-Function
The Riemann zeta-function embodies both additive and multiplicative structures in a single function, making it our most important tool in the study of prime numbers. This volume studies all aspects
New Vacca-Type Rational Series for Euler's Constant and Its
We recall a pair of logarithmic series that reveals ln(4 ∕ π) to be an “alternating” analog of Euler’s constant γ. Using the binary expansion of an integer, we derive linear, quadratic, and cubic
Double integrals and infinite products for some classical constants via analytic continuations of Lerch’s transcendent
The two-fold aim of the paper is to unify and generalize on the one hand the double integrals of Beukers for ζ(2) and ζ(3), and of the second author for Euler’s constant γ and its alternating analog
We describe a computation of the first 20,000 partial quotients in the regular continued fraction fo Euler’s constant = 0.577... and exp( ) = 1.781.... A preliminary step was the calculation of and
On the arithmetic nature of the values of the gamma function, Euler's constant, and Gompertz's constant
In this paper, we prove some results concerning the arithmetic nature of the values of the Gamma function at rational or algebraic points and for Euler’s constant γ. A (completely open) conjecture of
On q-analogues of the Euler constant and Lerch's limit formula
We introduce and study a q-analogue γ(q) of the Euler constant via a suitably defined q-analogue of the Riemann zeta function. We show, in particular, that the value γ(2) is irrational. We also
On the computation of Euler’s constant
The computation of Eider’s constant, γ, to 3566 decimal places by a procedure not previously used is described. As a part of this computation, the natural logarithm of 2 has been evaluated to 3683
