Heisenberg equations of motion in the Caldirola-Montaldi procedure

In this paper the procedure of Caldirola and Montaldi is applied in the Heisenberg representation. It is also proved here that the introduction of the parameter τ contributes to the specification of a quantum-dissipative system, as exactly happens in the Schrodinger representation. As an example the case of the harmonic oscillator as well as that of the damped harmonic oscillator are examined.
