摘要	In this article, we present generalized polygamy relations for a superposition of the generalized W class state and vacuum. This class of states were shown to satisfy the strong monogamy relations in terms of the squared convex roof extended negativity [14]. Here we first present a polygamy relation in terms of the beta-th power of the linear entanglement of assistance when beta is an element of (0, 1] for the superposition of the generalized W class state and vacuum. Then we present a tighter polygamy relation for the class of states in terms of the linear entanglement of assistance under some constraints. At last, we present a class of mixed states in higher dimensional systems satisfying the tighter polygamy relations we present. (C) 2020 Elsevier B.V. All rights reserved.
