Consider an abelian variety A defined over a global field K and let L/K be a Z d -extension, unramified outside a finite set of places of K, with Gal(L/K ) = � . Let �(�) := Z p((� )) denote the Iwasawa algebra. In this paper, we study how the characteristic ideal of the �(�) -module X L, the dual p-primary Selmer group, varies when L/K is replaced by a strict intermediate Z e-extension.
