On bounds for total absolute curvature of surfaces in hyperbolic 3-space
[Quelques bornes pour la courbure totale de surfaces dans l'espace hyperbolique de dimension 3]
Comptes Rendus. Mathématique, Tome 336 (2003) no. 1, pp. 47-50.

Nous construisons des exemples de surfaces dans l'espace hyperbolique qui ne satisfont pas l'inégalité de Chern–Lashof (qui est vérifiée pour les surfaces immergées dans l'espace euclidien).

We construct examples of surfaces in hyperbolic space which do not satisfy the Chern–Lashof inequality (which holds for immersed surfaces in Euclidean space).
