Some pinching theorems for minimal submanifolds in
Let M n be an n -dimensional compact minimal submanifolds in . We prove two pinching theorems by the Ricci curvature and the sectional curvature pinching conditions respectively. In fact, we characterize the Clifford tori and Veronese submanifolds by our pinching conditions respectively.
