“…Applying the monogamy relations in [20] to quantum correlations like squared convex-roof extended negativity, entanglement of formation, and concurrence one can get tighter monogamy inequalities than those given in [9]. In [21,22], Jin et al gave another set of monogamy relations for (0 ⩽ α ⩽ γ 2 , γ ⩾ 2) and polygamy relations for (β ⩾ δ, 0 ⩽ δ ⩽ 1), the bound is stronger than [20] in the monogamy case but weaker in polygamy case. Recently, Zhang et al [23] rigorously proved that their monogamy and polygamy are tighter than those given in [20][21][22].…”
