Margot Bruneaux, Federico Scavia

Let $R$ be a Henselian local ring, let $κ$ be the residue field of $R$ , let $C$ be a smooth projective curve over $R$ with geometrically connected fibers, let $G$ be a reductive $C…

Homogeneous spaces over an abelian variety

Margot Bruneaux

In this paper, we study a question of Colliot-Thélène and Iyer concerning the existence of rational sections in families of homogeneous spaces over an abelian variety, after base c…
