Hence all eigenvalues are 0 and so .=0. In the infinite-dimensional case however it is possible that an operator be semi-normal without being norma

Andropov and the Intensification of Labour,nics, . and . correspond to the unperturbed and total Hamiltonian respectively and . transforms the state at time . (interaction picture) into that at time . = 0 (Heisenberg picture); see, e.g., Friedrichs [3], Jauch [1] and Jauch and Zinnes [1].
