For the continuation of the research project "Representability Conditions and Correlations" which has applications in physics, for one more year financial support is applied for.It is planned that the doctoral researcher continues his analysis of the representability condition for reduced 1- and 2-fernion density matrices by studying the quotient of these conditions under Bogolubov tranformations.It is further planned that he defines a metric that allows to measure the distance of a given fermion operator to the closest representable density matrix, thus reformulating representability as a geometric approximation problem.
