$L^2$-extension theorems for jet sections of nef holomorphic vector   bundles on compact K\"ahler manifolds and rational homogeneous manifolds, I
  In this paper we study holomorphic vector bundles with singular Hermitian metrics whose curvature are Hermitian matrix currents. We obtain an extension theorem for holomorphic jet sections of nef holomorphic vector bundle on compact K\"ahler manifolds. Using it we prove that Fano manifolds with strong Griffiths nef tangent bundles are rational homogeneous spaces.
