references: Moor [Bull. Amer. Math. Soc. Vol.33 • No. 3 • May-June 1927 : "The results are for the most part due to the author himself, and the majority of them appear here in print for the first time. The work as a whole is a development of the methods of Tchebycheff in the study of the field indicated by the title.[...] the book has to a very great extent that admirable characteristic of the Borel series: namely, that its interest lies not only in the topics specifically treated, but also in the variety of problems for further research that are either definitely indicated or incidentally suggested."].
