....next proposition does not depend on the assumption that L(E=K; 1) is nonzero. Proposition 2.3 corank p Sel p 1 (E=K1 ) corank p Sel p 1 (E=K) 1. Proof of Proposition 2. 1 The structure theory of discrete modules shows that corank Sel p 1 (E=K1 ) corank p Sel p 1 (E=K1 ) See [M], ch. 1, or also [L] ch. 5, sec. 3, for details. But the propositions 2.2 and 2.3 imply that the p corank of Sel p 1(E=K1 ) is 1. It remains to prove proposition 2.3. Write Kn for the sub eld of K1 having degree p n over K, and Gn for the Galois group Gal(Kn=K) Let Kn0 , with n 0 0 be ....
....n 2 . But the point n2 has in nite order, and therefore it cannot be in nitely divisible in E(Kn2 ) Proof of Proposition 3.1 By corollary 3.3, E(K1 ) p = p has in nite p corank. On the other hand, a cotorsion module has nite p corank, by the structure theory of discrete modules ([M], ch. 1) This completes the proof of proposition 3.1, and of theorem 1.1. The next result gives information on the growth of the Mordell Weil groups E(Kn ) Proposition 3.4 If L(E=K; 1) is non zero, then there is a sequence of integers n having absolute value bounded independently of n such ....
