comment Duality for rank one modules over a number ring
@Marguaux: I decided to ask on MO the original question I had, which motivates the one asked here. Here is the link: mathoverflow.net/questions/141340/…

comment Duality for rank one modules over a number ring
Thanks for the nice answer and for giving my question some more appropriate context (I got the question from looking at subgroups of ordinary abelian varieties over a finite field. In the situation I had in mind R is Z[\pi], where \pi is an ordinary Weil-number).

thanks. you link gives only the definition of cesaro mean, however.

@Neil: I see, thanks.

comment Convergence at the radius of convergence
Wouldn't uniform convergence on your disk imply that your function admits its derivative at the branch point? (By a "switch-sum-and-differentiation"-type argument.. Or am I wrong?)

comment (phi, Gamma) module of ordinary elliptic curve
What if we give ourself the knowledge of the j-invariant of E? Do you think that using j_E one can say more about the structure of $T_p(E)$?

comment In which ways can the isogeny theorem fail for local fields?
I believe that if you are working with a $K$-isogeny class of elliptic curves whose members have rings of $K$-endomorphisms larger than $\mathbf{Z}$, then the isogeny theorem works.

comment Decomposition of primes in Galois closures of number fields
Nice example, thanks! I guess the question remains of whether the original question has a positive answer in the case where p is known to be tamely ramified. As we already decided, since inertia groups are cyclic in this case, the ramification of p in M/K is lcm of the ramification indeces in L/K. But what about f?
