The correspondence between the real and imaginary parts of mass operators at finite temperature and nonzero chemical potential is discussed using the real- and imaginary-time representations. Within the single-loop approximation, the imaginary part of the electron energy shift in a static uniform magnetic field at finite temperature and nonzero chemical potential is calculated and its physical interpretation is given. In the limiting cases, asymptotic expressions for the imaginary part of the electron energy shift are obtained, its zero-field finite-T value being zero. 25 refs.
