On the first Steenrod square for Chow groups

Olivier Haution

We construct a weak version of the homological first Steenrod square, a natural transformation from the modulo two Chow group to the Chow group modulo two and two-torsion. No assum…

Actions of diagonalizable $p$ -groups and Chern numbers modulo $p$

Olivier Haution

We obtain lower bounds for the dimension of fixed loci of diagonalizable $p$ -groups acting on smooth projective varieties. Those bounds depend on the modulo $p$ Chern numbers of th…
