某些对数系数三角级数的求和

Summation of certain trigonometric series with logarithmic coefficients

Rufus Boyack

摘要:

推广了Lerch首先利用的一种方法,导出了三个对数系数三角级数的和.通过对其中两个级数应用Frullani定理,利用双Γ函数计算了两个涉及双曲函数的非平凡积分.

英文摘要:

The sums of three trigonometric series with logarithmic coefficients are derived by extending an approach first utilized by Lerch. By applying Frullani's theorem to two of these series, two non-trivial integrals involving hyperbolic functions are evaluated in terms of the digamma function.
