Query: On PPT States in KxMxN Composite Quantum Systems   We study the general representations of positive partial transpose (PPT)
states in ${\cal C}^K \otimes {\cal C}^M \otimes {\cal C}^N$. For the PPT
states with rank-$N$ a canonical form is obtained, from which a sufficient
separability condition is presented.
