Two theorems on -Sasakian manifolds.
We deal with complete submanifolds with weighted Poincaré inequality. By assuming the submanifold is -stable or has sufficiently small total curvature, we establish two vanishing theorems for harmonic -forms, which are extensions of the results of Dung-Seo and Cavalcante-Mirandola-Vitório.
In this paper, we obtain some pinching theorems for totally real minimal submanifolds in complex projective space.
