摘要: In this paper, we consider the infinitesimal -and -isometry deformations of submanifolds immersed in a space form N of constant curvature. We obtain some results which are new even in the case of N being the Euclidean space. At the same time, we generalize some classical results in E3 to the submanifolds immersed in a space form of constant curvature.
