Abstract: | We study a complete noncompact minimal submanifold M n in a sphere S n+p . We prove there is no nontrivial L 2 harmonic 1-form and at most one nonparabolic end on M if the total curvature is bounded from above by a constant depending only on n. The rigidity theorem is a generalized version of Ni’s, Yun’s and the second author’s results on submanifolds in Euclidean spaces and Seo’s result on minimal submanifolds in hyperbolic spaces. |
