    "abstract": "The quantum entanglements are studied in terms of the invariants under local\nunitary transformations. A generalized formula of concurrence for\n$N$-dimensional quantum systems is presented. This generalized concurrence has\npotential applications in studying separability and calculating entanglement of\nformation for high dimensional mixed quantum states.",
