    "abstract": "For a given pure state of multipartite system, the concurrence vector is\ndefined by employing the defining representation of generators of the\ncorresponding rotation groups. The norm of concurrence vector is considered as\na measure of entanglement. For multipartite pure state, the concurrence vector\nis regarded as the direct sum of concurrence subvectors in the sense that each\nsubvector is associated with a pair of particles. It is proposed to use the\nnorm of each subvector as the contribution of the corresponding pair in\nentanglement of the system.",
