Abstract
We investigate monogamy relations related to the Rényi-α entanglement and polygamy relations related to the Rényi-α entanglement of assistance. We present new entanglement monogamy relations satisfied by the μ-th power of Rényi-α entanglement with αin\[sqrt{7}-1)/2,\(sqrt{13}-1\)/2\] for μgeqslant2, and polygamy relations satisfied by the μ-th power of Rényi-α entanglement of assistance with αin\[sqrt{7}-1)/2,\(sqrt{13}-1\)/2\] for 0leqμleq1. These relations are shown to be tighter than the existing ones.
