Abstarct: We will talk on the problem on the comparsion between
periods and petterson innert product of modular forms. Such kind of
problems turns out to be one of the key ingredients in the proofs of
Fermat last theorem and p-adic Birch Swinnerton-Dyer conjecture.
Two different approaches based on the non-vanishing modulo p of
L-values and the techniques from the modularity lifting theorems will
be discussed.
