One more proof of Siegel's theoremArticle

Authors: K Ramachandra 1

This paper gives a new elementary proof of the version of Siegel's theorem on L(1,χ)=n=1χ(n)n1 for a real character χ(modk). The main result of this paper is the theorem: If 3k1k2 are integers, χ1(modk1) and χ2(modk2) are two real non-principal characters such that there exists an integer n>0 for which χ1(n)χ2(n)=1 and, moreover, if L(1,χ1)1040(logk1)1, then L(1,χ2)>104(logk2)1(logk1)2k40000L(1,χ1)2. From this the result of T. Tatuzawa on Siegel's theorem follows.
