A new characterization of \(r\)-stable hypersurfaces in space forms. (English) Zbl 1249.53081

The \(r\)-stability of closed hypersurfaces with constant \(r\)-mean curvature in Riemannian manifolds of constant sectional curvature is studied. \(r\)-stable hypersurfaces are characterized through the first eingenvalue of an operator naturally attached to the \(r\)-mean curvature.
