A characterization theorem for matrix variances
Some recent papers formulated sufficient conditions for the decomposition of matrix variances [6,10]. A statement was that if we have one or two observables, then the decomposition is possible. In this paper we consider an arbitrary finite set of observables and we present a necessary and sufficient...
