Query: Lower Bound of Multipartite Concurrence Based on Sub-quantum State
  Decomposition   We study the entanglement of tripartite quantum states and provide analytical
lower bound of concurrence in terms of the concurrence of sub-states. The lower
bound may improve all the existing lower bounds of concurrence. The approach is
generalized to arbitrary dimensional multipartite systems.
