probabilistic problems in the calculus of variatof M. Putinar which states that each hyponormal operator is subscalar, i.e. the restriction of an operator generalized scalar in the sense of C. Foiaş. In an attempt to generalize S. Brown's result to the context of arbitrary Banach spaces \textit{E. Albrecht} and \textit{B. Chevreau} proved that each restriction or quotient of a decomposable operator
