We consider embedded hypersurfaces M in hyperbolic space with compact boundary C and some r(th) mean curvature function H_r a positive constant. We investigate when symmetries of C are symmetries of M. We prove that if 0 less than or equal to H_r less than or equal to 1 and C is a sphere then M is a part of an equidistant sphere. For r = 1 (H_1 is the mean curvature) we obtain results when C is convex.

Abstract
We consider embedded hypersurfaces M in hyperbolic space with compact boundary C and some r(th) mean curvature function H_r a positive constant. We investigate when symmetries of C are symmetries of M. We prove that if 0 less than or equal to H_r less than or equal to 1 and C is a sphere then M is a part of an equidistant sphere. For r = 1 (H_1 is the mean curvature) we obtain results when C is convex.File in questo prodotto:
