Monogamy properties of qubit systems

We investigate monogamy relations related to quantum entanglement for $n-$qubit quantum systems. General monogamy inequalities are presented to the $\beta$th $(\beta \in (0,2))$ power of concurrence, negativity and the convex-roof extended negativity, as well as the $\beta$th $(\beta \in (0,\sqrt{2}))$ power of entanglement of formation. These monogamy relations are complementary to the existing ones with different regions of parameter $\beta$. In additions, new monogamy relations are also derived which include the existing ones as special cases.
