Abstract
We presented a general classification scheme for the tripartite $L\ifmmode\times\else\texttimes\fi{}N\ifmmode\times\else\texttimes\fi{}N$ entangled system under stochastic local operation and classical communication. The whole classification procedure consists of two correlated parts: the simultaneous similarity transformation of a commuting matrix pair into a canonical form and the study of internal symmetry of parameters in the canonical form. Based on this scheme, a concrete example of entanglement classification for a $3\ifmmode\times\else\texttimes\fi{}N\ifmmode\times\else\texttimes\fi{}N$ system is given.
