نویسندگان

چکیده

Let k be a field, T an algebraic k-torus, X smooth k-compactification of and PicX‾ the Picard group X‾=X×kk‾. Hoshi, Kanai Yamasaki [HKY22] determined H1(k,PicX‾) for norm one tori T=RK/k(1)(Gm) gave necessary sufficient condition Hasse principle extensions K/k number fields with [K:k]=n≤15 n≠12. In this paper, we determine 64 cases H1(k,PicX‾)≠0 give [K:k]=12.

The Proportion of Failures of the Hasse Norm Principle

For any number field we calculate the exact proportion of rational numbers which are everywhere locally a norm but not globally a norm from the number field.

Incompressibility of Generic Torsors of Norm Tori

Let p be a prime integer, F a field of characteristic not p, T the norm torus of a degree p extension field of F , and E a T -torsor over F such that the degree of each closed point on E is divisible by p (a generic T -torsor has this property). We prove that E is p-incompressible. Moreover, all smooth compactifications of E (including those given by toric varieties) are p-incompressible. The m...

Trace and Norm, Ii

where σ1(α), . . . , σd(α) are all the distinct values of σ(α) as σ runs over the Galois group. For each σ ∈ G, σ(α) = σi(α) for a unique i from 1 to d. Moreover, σ(α) = σi(α) if and only if σ ∈ σiH, where H = {τ ∈ G : τ(α) = α} = Gal(L/K(α)). Therefore as σ runs over G, the number σi(α) appears as σ(α) whenever σ is in the left coset σiH, so σi(α) occurs |H| times, and |H| = [L : K(α)] = [L : ...

Norm-euclidean Cyclic Fields of Prime Degree

Let K be a cyclic number field of prime degree `. Heilbronn showed that for a given ` there are only finitely many such fields that are normEuclidean. In the case of ` = 2 all such norm-Euclidean fields have been identified, but for ` 6= 2, little else is known. We give the first upper bounds on the discriminants of such fields when ` > 2. Our methods lead to a simple algorithm which allows one...

Implications of the Hasse Principle for Zero Cycles of Degree One on Principal Homogeneous Spaces

Let k be a perfect field of virtual cohomological dimension ≤ 2. Let G be a connected linear algebraic group over k such that Gsc satisfies a Hasse principle over k. Let X be a principal homogeneous space under G over k. We show that if X admits a zero cycle of degree one, then X has a k-rational point. Introduction The following question of Serre [10, p. 192] is open in general. Q: Let k be a ...
