Query: Tighter monogamy and polygamy relations of multiparty quantum
  entanglement   We investigate the tight monogamy and polygamy relations of multiparty
entanglement for arbitrary quantum states. By using the power of the bipartite
measure of entanglement, we establish a class of tight monogamy relations of
multiparty entanglement with larger lower bounds than the existing monogamy
relations. We also give a class of tight polygamy relations of multiparty
entanglement with smaller upper bounds than the existing polygamy relations, by
using the power of the entanglement of assistance. It is shown that these new
monogamy and polygamy relations are tighter than the former results.
