Abstract: | In this paper, we prove that the only compact two-sided hypersurfaces with constant mean curvature H which are weakly stable in
and have constant scalar curvature are (i) the twofold covering of a totally geodesic projective space; (ii) the geodesic spheres in
; and (iii) the quotient to
of the hypersurface
obtained as the product of two spheres of dimensions k and n − k, with k = 1,..., n − 1, and radii r and
, respectively, with
