Herissons et multiherissons (enveloppes parametrées par leur application de Gauss) Rémi Langevin, Harold Rosenberg (1988) Banach Center Publications
Hypersurfaces with constant curvature in ℝ n + 1 J. A. Gálvez, A. Martínez (2002) Banach Center Publications We give some optimal estimates of the height, curvature and volume of compact hypersurfaces in ℝ n + 1 with constant curvature bounding a planar closed (n-1)-submanifold.
