论文摘要
我们为使用$ 1/\ cos(x/4)$的傅立叶系列扩展和应用Parseval-Plancherel身份提供了双系列公式。我们表明,这样的公式涉及粒状 - 基里维丁常数,因此后者也可以表示为双重系列。
We provide a double-series formula for $π$ obtained using the Fourier series expansion of $1/\cos(x/4)$ and applying the Parseval-Plancherel identity. We show that such a formula involves the Grothendieck-Krivine constant, and that the latter can therefore be expressed as a double series as well.
