Journal:	Commun. Theor. Phys. 42 (2004) 215-222
Subject:	quant-ph
Abstract:	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.
