Arithmetic on Modular Curves by G. Stevens

By G. Stevens

One of the main interesting difficulties of contemporary quantity thought is to narrate the mathematics of abelian forms to the unique values of linked L-functions. a really designated conjecture has been formulated for elliptic curves by means of Birc~ and Swinnerton-Dyer and generalized to abelian forms via Tate. The numerical facts is sort of encouraging. A weakened type of the conjectures has been established for CM elliptic curves by way of Coates and Wiles, and lately reinforced by means of ok. Rubin. yet a normal facts of the conjectures turns out nonetheless to be a ways off. many years in the past, B. Mazur [26] proved a vulnerable analog of those c- jectures. permit N be major, and be a weight newform for r zero (N) . For a primitive Dirichlet personality X of conductor top to N, allow i\ f (X) denote the algebraic a part of L (f , X, 1) (see below). Mazur confirmed in [ 26] that the residue type of Af (X) modulo the "Eisenstein" excellent supplies information regarding the mathematics of Xo (N). There are elements to his paintings: congruence formulae for the values Af(X) , and a descent argument. Mazur's congruence formulae have been prolonged to r 1 (N), N top, by way of S. Kamienny and the writer [17], and in a paper in an effort to look almost immediately, Kamienny has generalized the descent argument to this case.
