Abstract
We consider the separability of various joint states for N qutrits. We deri ve two results: (i) the separability condition for a two-qutrit state that is a mixture of the maximally mixed state and a maximally entangled state ( such a state is a generalization of the Werner state for two qubits); (ii) upper and lower bounds on the size of the neighborhood of separable states surrounding the maximally mixed state for N qutrits.
