The Hasse principle for finite Galois modules allowing exceptional sets of positive density
نویسندگان
چکیده
We study a variant of the Hasse principle for finite Galois modules, allowing exceptional sets positive density. For module whose underlying abelian group is isomorphic to [Formula: see text] ([Formula: text]), we show that product restriction maps places in set injective if Dirichlet density strictly larger than text]. give applications local–global divisibility problem elliptic curves and flexes on plane cubic curves.

Let k be a field of characteristic 6= 2, and let L be a Galois extension of k with group G. Let us denote by qL : L × L → k the trace form, defined by qL(x, y) = TrL/k(xy). Let (gx)g∈G be a normal basis of L over k. We say that this is a self–dual normal basis if qL(gx, hx) = δg,h. If the order of G is odd, then L always has a self–dual normal basis over k (cf. [1]). This is no longer true in g...
متن کاملOn the Hasse Principle for Shimura Curves
Let C be an algebraic curve defined over a number field K, of positive genus and without K-rational points. We conjecture that there exists some extension field L over which C violates the Hasse principle, i.e., has points everywhere locally but not globally. We show that our conjecture holds for all but finitely many Shimura curves of the form XD 0 (N)/Q or X D 1 (N)/Q, where D > 1 and N are c...
متن کاملCounterexamples to the Hasse Principle
This article explains the Hasse principle and gives a self-contained development of certain counterexamples to this principle. The counterexamples considered are similar to the earliest counterexample discovered by Lind and Reichardt. This type of counterexample is important in the theory of elliptic curves: today they are interpreted as nontrivial elements in Tate– Shafarevich groups.
متن کاملCounterexamples to the Hasse principle
In both of these examples, we have proved that X(Q) = ∅ by showing that X(Qv) = ∅ for some place v. In the first case it was v = ∞, the real place. In the second case we showed that X(Q2) was empty: the argument applies equally well to a supposed solution over Q2. Given a variety X over a number field k and a place v of k, it is a finite procedure to decide whether X(kv) is empty. Moreover, X(k...
