Abstract
The parameterized entanglement monotone, the -concurrence, is also a reasonable parameterized entanglement measure. By exploring the properties of the -concurrence with respect to the positive partial transposition and realignment of density matrices, we present tight lower bounds of the -concurrence for arbitrary . Detailed examples are given to show that the bounds are better than the previous ones.
