Domain characterizations of strong commutativity of unbounded self‐adjoint operators
Konrad SchmüdgenAbstract
Let and be unbounded self‐adjoint operators on a Hilbert space. Suppose that there exists a dense linear subspace such that for . We give some characterizations of the strong commutativity of and in terms of domain equalities.
