Abstract
We obtain the Wang-type integral inequalities for compact minimal hypersurfaces in the unit sphere S 2 n + 1 with Sasakian structure and use these inequalities to find two characterizations of minimal Clifford hypersurfaces in the unit sphere S 2 n + 1 .
Highlights
Let M be a compact minimal hypersurface of the unit sphere Sn+1 with shape operator A
Simons [1] has shown that on a compact minimal hypersurface M of the unit sphere Sn+1 either A = 0, or k Ak2 = n, or k Ak2 ( p) > n for some point p ∈ M, where k Ak is the length of the shape operator
If for every point p in M, the square of the length of the second fundamental form of M is n, it is known that M must be a subset of a Clifford minimal hypersurface r !
