✦ Synopsis

Expressions mo derived that bound from above the Helmhoitz free energy of a &as&cat system.

Letf be the Helmholta free energy per particle, p *he number density, andg(r) the pair fra-dial} distribution function of a classical singiespecies system, the energy of which is a sum of one-body and two-body contributions. If the pair potential u(r) is arbitrariLy decomposed into the sum of two terms, U(T) =u"(r)

## Abstract It is known that a planar graph on __n__ vertices has branch‐width/tree‐width bounded by $\alpha \sqrt {n}$. In many algorithmic applications, it is useful to have a small bound on the constant α. We give a proof of the best, so far, upper bound for the constant α. In particular, for th
