Abstract: |
In this paper, the authors study the generic submanifolds with 2-Harmonic in a complex projective space. By method of moving frame, we obtain a pinching theorems of generic submanifolds is minimal and a promotion of J. Simons' type integral inequality. Moreover, the authors also obtain some rigidity theorems of the generic submanifolds with 2-Harmonic and psedu-umbilical and improve the results of the totally real submanifolds with 2-Harmonic in a complex projective space. |
