AbstractWe consider a class of positive linear maps in the three-dimensional matrix algebra, which are generalizations of the positive linear map constructed by Choi in the relation with positive semidefinite biquadratic forms. We find conditions for which such maps are completely positive, completely copositive, decomposable, and two-positive
