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 本文主要研究復射影空間中的全實偽臍子流形:討論它們的構造,并給出具體例子
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).
