Abstract

A problem of further generalization of generalized Choi maps Φ_[a,b,c] acting on \mathbbM₃ introduced by Cho, Kye and Lee is discussed. Some necessary conditions for positivity of the generalized maps are provided as well as some sufficient conditions. Also some sufficient condition for decomposability of these maps is shown.
