A counterexample to a conjecture of Duncan on versal actions
Federico Scavia
We disprove a conjecture of Duncan asserting that versality of a faithful finite group action can be detected on Sylow subgroups. Our counterexample is an action of $(C_7\rtimes C_…
Zero-cycles on surfaces dominated by products of hyperelliptic curves
Jean-Louis Colliot-Thélène, Federico Scavia, Alexei Skorobogatov
Conditionally on the finiteness of the relevant Tate-Shafarevich groups, we prove a local-to-global result for zero-cycles of degree on the surfaces given by $y^2 = f_1(x_1)f_2…
Variétés réelles connexes non stablement rationnelles
Jean-Louis Colliot-Thélène, Alena Pirutka, Federico Scavia
Let be the field of real Puiseux series. It is a real closed field. We construct the first examples of smooth intersections of two quadrics in and smooth cubic…
Sur l'injectivité de l'application cycle de Jannsen
Jean-Louis Colliot-Thélène, Federico Scavia
For specific classes of smooth, projective varieties over a field , we compare two cycle maps on the torsion subgroup of the second Chow group. The…
Autour de la conjecture de Tate entière pour certains produits de dimension sur un corps fini
Federico Scavia
Let be the product of a surface satisfying and of a curve over a finite field. We study a strong form of the integral Tate conjecture for -cycles on . We generali…
Sur la conjecture de Tate entière pour le produit d'une courbe et d'une surface -triviale sur un corps fini
Jean-Louis Colliot-Thélène, Federico Scavia
We investigate a strong version of the integral Tate conjecture for 1-cycles on the product of a curve and a surface over a finite field, under the assumption that the surface is g…
