Abstract
In this paper, we study the ααth power monogamy properties related to the entanglement measure in bipartite states. The monogamy relations related to the ααth power of negativity and the Convex-Roof Extended Negativity are obtained for NN-qubit states. We also give a tighter bound of hierarchical monogamy inequality for the entanglement of formation. We find that the GHZ state and W state can be used to distinguish both the ααth power of the concurrence for 0<α<20<α<2 and the ααth power of the entanglement of formation for 0<α≤12. Furthermore, we compare concurrence with negativity in terms of monogamy property and investigate the difference between them.
