Abstract:Abstract. We prove a functional equation for two projective systems of finite abelian p-groups, {an} and {bn}, endowed with an action of Z d p such that an can be identified with the Pontryagin dual of bn for all n.Let, unramified outside a finite set of places. Let A be an abelian variety over K. We prove an algebraic functional equation for the Pontryagin dual of the Selmer group of A.
“…It turns out that when L contains the arithmetic Z p -extension the Frobenius part is a direct sum of twisted eigenspaces of class group (see Proposition 3.4.2), and hence its characteristic ideal can be determined by applying the Iwasawa Main Theorem of class groups [Crw87]. To deal with the Verschiebung part, we make use of the algebraic functional equation proved in [LLTT1]. These together lead to the proof of the theorem under the condition that L contains the arithmetic Z p -extension.…”
Abstract. We study a geometric analogue of the Iwasawa Main Conjecture for constant ordinary abelian varieties over Z d p -extensions of function fields ramifying at a finite set of places.
