    The authors study a \(2\times 2\) operator matrix associated with a closed densely defined operator. Among other results, the selfadjointness of a closed symmetric operator and the strong commutativity of two (unbounded) selfadjoint operators are characterized in terms of the related operator matrices. They also propose a definition of strong commutativity for closed symmetric operators.
