Two approaches in treating the weak representability problem for density operators are studied. In the first approach this problem is reduced to the minimization of a certain distance function. The second approach is based on inductive generation of linear inequalities for diagonal elements of the second‐order density operators. Generalization of Kuhn–Yoseloff's results is also discussed.
