In this paper , we mainly study the totally real pseudo - umbilical sub - manifolds of a complex projective space : we discuss how to construct them and give the examples 本文主要研究复射影空间中的全实伪脐子流形:讨论它们的构造,并给出具体例子
In mathematics, complex projective space is the projective space with respect to the field of complex numbers. By analogy, whereas the points of a real projective space label the lines through the origin of a real Euclidean space, the points of a complex projective space label the complex lines through the origin of a complex Euclidean space (see below for an intuitive account).
