From the Schaar and L\"osch-Schoblick integrals to representations of the Glaisher-Kinkelin constant
Abstract
In this article, we present two integral representations of the logarithm of the Glaisher-Kinkelin constant, relying on two different integral formulations of the so-called Binet function μ(x). The first one is attributed to Schaar (and also often referred to as ``the second Binet formula''), and the second one is due to L\"osch and Schoblik. It seems that the two new expressions (formulas (28) and (33) of the present article) of the Glaisher-Kinkelin constant, can not be easily deduced from know ones.
