카탈란 상수

간단한 소개

\(G = \beta(2) = \sum_{n=0}^{\infty} \frac{(-1)^{n}}{(2n+1)^2} = \frac{1}{1^2} - \frac{1}{3^2} + \frac{1}{5^2} - \frac{1}{7^2} + \cdots \!\)

여기서 

\(\beta(s) = \sum_{n=0}^\infty \frac{(-1)^n} {(2n+1)^s}\) 

\(\beta(s) = \frac{1}{\Gamma(s)}\int_0^{\infty}\frac{x^{s-1}e^{-x}}{1 + e^{-2x}}\,dx\)
