Let GG be a nontrivial finite étale tame group scheme over a global field F F. We define height functions on the set of GG‐torsors over FF, which generalize the usual heights such …

We consider the problem of counting the number of varieties in a family over Q with a rational point. We obtain lower bounds for this counting problem for some families over P1 …

We construct an analogue of the classical descent theory of Colliot-Thélène and Sansuc in which algebraic tori are replaced with finite supersolvable groups. As an application, we …

Given a number field $ k $ and a finitely generated subgroup $\mathcal {A}\subseteq k^* $, we study the distribution of $ S_4 $-quartic extensions of $ k $ such that the elements of …

Let AA be a finite, abelian group. We show that the density of AA‐extensions satisfying the Hasse norm principle exists, when the extensions are ordered by discriminant. This …

The inverse Galois problem asks whether any finite group can be realised as the Galois group of a Galois extension of the rationals. This problem and its refinements have …

Let K/k be an extension of number fields. We describe theoretical results and computational methods for calculating the obstruction to the Hasse norm principle for K/k and the defect of …
