本文改进了S.T.Yau(文[1])中关于单位球面中具有平行平均曲率向量场的子流形的一个结果。然而从截面曲率这一角度出发,给出了空间形式R^n+p(c)(n>1,p>1)中具有平行平均曲率向量场的可定向闭子流形M^n的有关结果和积分不等式。 相似文献

In this paper, infinitesimal deformations of time-like surfaces are investigated in Minkowski 3-space R^2,1. It is shown that some given deformations of the time-like surface can be described by 2 1 dimensional integrable systems. Moreover spectral parameters are introduced, and it is proved that deformation families are soliton surfaces‘ families. 相似文献
