Cohomology of real algebraic varieties and sums of squares

Appears in collection : Géométrie algébrique en l'honneur de Claire Voisin

I will describe relations between Chern classes and constant cohomology classes in the cohomology of real algebraic varieties. I will give applications to sums of squares problems. This is joint work with Olivier Wittenberg.
