英文摘要	Let M be a complex manifold. We prove that a compact submanifold S subset of M with splitting tangent sequence (called a splitting submanifold) is rational homogeneous when M is in a large class of rational homogeneous spaces of Picard number one. Moreover, when M is irreducible Hermitian symmetric, we prove that S must be also Hermitian symmetric. These cover some of the results given in Jahnke (Math Z 251(3):491-507, https://doi.org/10.1007/s00209-005-0817-6, 2005). The basic tool we use is the restriction and projection map pi of the global holomorphic vector fields on the ambient space which is induced from the splitting condition. The usage of global holomorphic vector fields may help us set up a new scheme to classify the splitting submanifolds in explicit examples, as an example we give a differential geometric proof for the classification of compact splitting submanifolds with dim >= 2 in a hyperquadric, which has been proven in Jahnke (2005) using algebraic geometry.
