Complexe de poids des variétés algébriques réelles avec action
Fabien Priziac
Using the functoriality of C. McCrory and A. Parusiński's weight complex -which induces an analog of the weight filtration for complex algebraic varieties on the Borel-Moore homolo…
An explicit expression of the Luroth invariant
Romain Basson, Reynald Lercier, Christophe Ritzenthaler +1
In this short note, we give an algorithm to get an explicit expression of the Luroth invariant in terms of the Dixmier-Ohno invariants. We also get the explicit factorized expressi…
The Tate conjecture for K3 surfaces over finite fields
François Charles
Artin's conjecture states that supersingular K3 surfaces over finite fields have Picard number 22. In this paper, we prove Artin's conjecture over fields of characteristic p>3. Thi…
Cubic fourfolds containing a plane and a quintic del Pezzo surface
Asher Auel, Marcello Bernardara, Michele Bolognesi +1
We isolate a class of smooth rational cubic fourfolds X containing a plane whose associated quadric surface bundle does not have a rational section. This is equivalent to the nontr…
Fast computation of isomorphisms of hyperelliptic curves and explicit Galois descent
Reynald Lercier, Christophe Ritzenthaler, Jeroen Sijsling
We show how to speed up the computation of isomorphisms of hyperelliptic curves by using covariants. We also obtain new theoretical and practical results concerning models of these…
