comment Irreducibility of polynomials in two variables
Have a look at p. 116 of the document above. I only rewrote Ehrenfeucht's proof with a few more details. I can send you the original paper tomorrow, if you like.

comment History of spectral methods to the study of real analytic $GL_2$-Eisenstein series
I have in mind the book of Lax and Philips who applied scattering theory to the study of automorphic forms. In that book I saw for the first time a truncated version of the hyperbolic Laplacian which has a compact resolvent. Then from a key observation of Colin de Verdiere, one may apply the Fredholm analyticity theorem to obtain the analytic continuation and the functional equation. In any case, thanks again for your answer.

Dear Paul, thanks for portrait that you have brushed. Regarding your comment about Kubota's book I get your point but my feeling is that his book was probably the first comprehensive and accessible reference on $GL_2$-real analytic Eisenstein series for non-experts. Also in the nice portait that you just depicted, one should also probably mention the substantial contributions which came from physics and functional analysis.
