Abstract: | A generalized Kirkwood-Salsburg equation for a classical system of particles with an arbitrary stable interaction in an external potential σ(x) such that exp (- βσ) is integrable is derived. It is shown that the spectrum of the generalized Kirkwood-Salsburg operator consists of the inverses of the zeros of the grand canonical partition function. |
