Grassmann流形Gr(2+1,2)上的非线性联络

Nonlinear Connection in Grassmannian Manifold Gr(2 + 1,2)

本文介绍了Grassmann流形、主纤维丛联络的相关概念和定理。计算了以Gr(2+1,2)为纤维形上的非线性联络。

In this article, conceptions and relative theorems of Grassmannian manifold and connection of prin- cipal fiber bundle were introduced. Compute the nonlinear connection of fiber bundle was calculated, in which fiber is Gr （2＋1, 2）.
