Squares of positive (p,p)-forms
[Carrés de (p,p)-formes positives]
Comptes Rendus. Mathématique, Volume 351 (2013) no. 1-2, pp. 27-32.

Nous montrons que si α est une (2,2)-forme positive alors α2 lʼest aussi. Nous prouvons également que ceci nʼest plus vrai pour les formes de degré supérieur.

We show that if α is a positive (2,2)-form, then so is α2. We also prove that this is no longer true for forms of higher degree.
