On Operator Sum and Product Adjoints and Closures
Published online by Cambridge University Press: 20 November 2018
Abstract
We comment on domain conditions that regulate when the adjoint of the sum or product of two unbounded operators is the sum or product of their adjoints, and related closure issues. The quantum mechanical problem $\text{PHP}$ essentially selfadjoint for unbounded Hamiltonians is addressed, with new results.
