Abstract: | In the complex Grassmann manifold ℱ(m,n), the space of complexn-planes passes through the origin of Cm+n; the local coordinate of the space can be arranged into anm ×n matrixZ. It is proved that is a U(m)-connection of ℱ(m,n) and its curvature form satisfies the Yang-Mills equation. Moreover, is an (Sum)-connection and its curvature form satisfies the Yang-Mills equation.
