A so-called quasientanglement measure was obtained J. Zhang et al., Phys. Rev. A 73, 022319 2006 by<BR>extending Jaeger’s Minkowskian norm entanglement measure to general multipartite mixed states. The obtained<BR>quasientanglement measure has good properties, but it is still left open whether it is nonincreasing under<BR>general local operations and classical communications LOCC. We show that the obtained quasientanglement<BR>measure is indeed nonincreasing on average un
