Remark on the Betti numbers for Hamiltonian circle actions
Comptes Rendus. Mathématique, Tome 359 (2021) no. 2, pp. 113-117.

Dans cet article, nous établissons une certaine inégalité en termes de nombres de Betti d’une S 1 -variété hamiltonienne avec des points fixes isolés.

In this paper, we establish a certain inequality in terms of Betti numbers of a closed Hamiltonian S 1 -manifold with isolated fixed points.
