“…-The possibility of the failure of Galois co-descent in Proposition 2.3 was already observed in [2]. The situations where this happens are easily described: First of all we must have i = 1 mod d and L f. We recall that by Lemma 2.1, the natural map…”

“…Results for arbitrary finite Galois p-extensions have been obtained by Assim (cp. [I], [2]) in terms of primitive ramification, however under the assumption that Leopoldt's Conjecture holds for the fields L(apn) for all n. Let S be the finite set of primes of F, consisting of the set Sp and the tamely ramified primes in L/F. We have the following exact sequence: is always surjective and that the kernel of this map is isomorphic to the cokernel of the map where S^ consists of the primes in L above S \ Sp.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
