Hence it follows that Im(XK)/Im(nK) is a finite group. On the other hand, GK has pcohomological dimension 1 because of the hypothesis that Gal(K/F,) contains an infinite pro-p subgroup. ) Thus if C is a divisible, pprimary GK-module, then the exact sequence 0 + C[p] + C 4 C + 0 induces the cohomology exact se, + H ~ ( K C[p]). , The last group is zero and quence H1(K, C ) 4 H ~ ( K C) hence H1(K, C ) is divisible. Applying this to C = C,, we see that Im(XK) is divisible and so Im(nK) = 1 m ( X ~ ) .

Suppose that F has only one prime lying over p and that this prime is totally ramified in F,/F. ) Then one can indeed recover Gal(Ln/Fn) from the A-module X . We have - The isomorphism is induced from the restriction map X + Gal(Ln/Fn). Here is a brief sketch of the proof: Gal(F,/Fn) is topologically generated by ypn; one verifies that (ypn - l ) X is the commutator subgroup of Gal(L,/Fn); and one proves that the maximal abelian extension of Fn contained in L, is precisely F,Ln. ) Then one notices that Gal(Ln/Fn) F Gal(F,L,/F,).

It depends on the Tate period q~ for E, which is defined by the equation j(qE) = jE, solving this equation for q~ E F c . , the image of q under the Kummer homomorphism M /(MX)pn -+ H1(M, ppn). 6 follows by just taking a direct limit. Still assuming that E has split, multiplicative reduction at v, the statement that ker(r,,) is finite is equivalent t o the assertion that ker(d,J Im(n,,). In this case, we show that I ker(r,,)l is bounded as n varies. For let = '~CF"(QE)I(F,)~E Gal((F,),/F,). Then we have '~C(F,,),,, ( Q E ) ~ ( F ~=) aen , .
