Abstract:
A new representation is derived for the Ursell functions. This representation is used,
in particular, to improve the already known estimates of the Ursell functions, the
estimates of the convergence radius of the Mayer expansion, and to derive cluster
estimates of the cluster functions (cf [1–5]).
