| ABSTRACT |
In this paper, we study the Fitting ideals of Selmer groups over finite subextensions in the cyclotomic Z(p)-extension of Q of an elliptic curve over Q. Especially, we present a proof of the "weak main conjecture" a la Mazur and Tate for elliptic curves with good (supersingular) reduction at an odd prime p. We also prove the "strong main conjecture" suggested by the second named author under the validity of the +/--main conjecture and the vanishing of a certain error term. The key idea is the explicit comparison among "finite layer objects", "+/--objects", and "fine objects" in Iwasawa theory. The case of good ordinary reduction is also treated. |
