| Abstract: | We use the generalized Frenet formulas to study the isotropy of harmonic maps from surfaces into complex Grassmann manifolds and provide a new sufEicient condidon to ensure the isotropy of hannonic maps. For non-isotropic harmonic maps we obtain a curvature Pinching property which depends on the isotropy order. |
