Abstract
The propagation of the operator average is described in truncated space with some quantum number(s) being fixed. It is first shown that the propagation coefficient satisfies an analog of the Chapman–Kolmogorov equation. Next, particle-hole symmetry is incorporated into the propagation of the operator average. It yields an expression that facilitates evaluation of many-body trace. Fermion and boson systems are treated alike.Keywords
