Abstract We expand upon work from many hands on the decomposition of nuclear maps. Such maps can be characterised by their ability to approximately written as composition and matrices. Under certain conditions (such quasidiagonality), we find a whose behave nicely, preserving multiplication up an arbitrary degree accuracy being constructed order-zero (as in definition dimension). investigate these relate them W*-analogue.
