AbstractIt has been conjectured that, ifp≡ 1 (mod 4) is prime, and ifd<0 is a square‐free discriminant with(dk)=−1,thenL(1, χk,G)=8πk√|d|log ε,Whereεka/2εbelongs to the fieldΩ(√k), εkis the fundamental unit ofQ(√k),χk(n)=(nk), a=0 or a=1depending on whether there are an even number or an odd number of classes per genus inQ(√d), and Ω is the genus field ofQ(√d). HereL(s, χk, G)=∑L(s, χk, Q),the summation being over a complete set of inequivalent forms in the genusG, andL(s, χk, Q)=12∑(x, y) ≠ (0, 0)χk(Q(x, y))Q(x, y)s.In this paper it will be shown that this conjecture is true whendis the product of two odd discriminants. An example whendis the product of three prime discriminants is discussed.
