Abstract We explore the existence of monogamy relations in terms of Rényi- α entanglement. By using the power of the Rényi- α entanglement, we establish a class of tight monogamy relations of multiqubit entanglement with larger lower bounds than the existing monogamy relations for α ≥ 2, the power η > 1, and 2 > α ≥ 7 − 1 2 , the power η > 2, respectively.
