My question is very simple :
My goal is to read a proof the proof of the epsilon conjecture proven by Ken Ribet (1986) which is an ingredient of the proof of the Fermat Last Theorem (I want the Ribet theorem not the FLT)
I have undergraduate knowledge in Galois theory, elliptic curves and modular forms. But I did not found any readable documents that gives the minimal prerequistes for the Ribet's theorem.
Is there someone who know if there is a book which proves this theorem ? Even if it is at a graduate level ! All I want is a clear road to understand this proof :)
Thank you.
