# Eisenstein series and the Kronecker limit theorem

It is well known that the first Kronecker limit theorem gives the Laurent expansion of the Eisenstein series $E(z,s)$ over $SL(2,Z)$ at $s=1$; see, for example, Serge Lang's book Elliptic Curves, Section 20.4.

My question is, is there an analogous formula for the Eisenstein series over congruence subgroups? This seems a natural question and I believe that it must be hidden somewhere in the literature, but I cannot find a reference.

Any help will be appreciated. Thanks!

Remark: Thanks to Anweshi's help, we can find the following papers.

I think you're looking for the theory of automorphic forms. – Steve Huntsman Jan 20 '10 at 20:20
Yes, but in a very classical language. – qiaozi Jan 21 '10 at 15:46
The book of Rademacher on analytic number theory may help with background on Dedekind sums. – Anweshi Jan 21 '10 at 17:38

Yes, there is a generalization. It was done by Larry Joel Goldstein, in the paper "Dedekind sums for a Fuchsian group". The paper has two parts and was published in the Nagoya Journal in around 1973-74.
