Let F be a number field with ring of integers OF , and letS be a finite set of places ofF . Assume that S contains the set S∞ of archimedean places of F , and write Sf for the set of finite places contained in S. Let OS (or O, when there is no danger of confusion) denote the ring of Sf -integers ofF . WriteF for an algebraic closure of F . LetY be any scheme over Spec (O). Suppose that G is a finite, flat commutative group scheme over Y of exponentN , and letG denote the Cartier dual of G. Let… CONTINUE READING
