Abstract

In this paper, we present some generalized monogamy inequalities and upper bounds of negativity based on convex-roof extended negativity (CREN) and CREN of assistance (CRENOA). These monogamy relations are satisfied by the negativity of N-qubit quantum systems ABC1CN2, under the partitions AB|C1CN2 and ABC1|C2CN2. Furthermore, the W-class states are used to test these generalized monogamy inequalities.
