We revisit the expansion recently proposed by Pulvirenti and Tsagkarogiannis for a system of N continuous particles in the Canonical Ensemble. Under the sole assumption that the particles interact via a tempered and stable pair potential and are subjected to the usual free boundary conditions, we show the analyticity of the Helmholtz free energy at low densities and, using the Penrose tree graph identity, we establish a lower bound for the convergence radius which happens to be identical to the…

The virial series for a gas of particles with uniformly repulsive pairwise interaction and its relation with the approach to the mean field
D. Marchetti
. The pressure of a gas of particles with a uniformly repulsive pair interaction in a finite container is shown to satisfy (exactly as a formal object) a "viscous" Hamilton–Jacobi (H–J) equation whose…

Convergence of Density Expansions of Correlation Functions and the Ornstein–Zernike Equation
T. Kuna, D. Tsagkarogiannis
We prove absolute convergence of the multi-body correlation functions as a power series in the density uniformly in their arguments. This is done by working in the context of the cluster expansion in…

Virial Expansion Bounds
S. Tate
In the 1960s, the technique of using cluster expansion bounds in order to achieve bounds on the virial expansion was developed by Lebowitz and Penrose (J. Math. Phys. 5:841, 1964) and Ruelle…
Fe b 20 14 A SOLUTION TO THE COMBINATORIAL PUZZLE OF MAYERS VIRIAL
Mayer's second theorem in the context of a classical gas model allows us to write the coefficients of the virial expansion of pressure in terms of weighted two-connected graphs. Labelle, Leroux and…
Cluster Expansion for the Ising Model in the Canonical Ensemble

We show the validity of the cluster expansion in the canonical ensemble for the Ising model. We compare the lower bound of its radius of convergence with the one computed by the virial expansion…
Virial Expansion Bounds Through Tree Partition Schemes
S. Ramawadh, S. Tate
The bound on the radius of convergence in the case of the Penrose partition scheme is the same as that proposed by Groeneveld and improves the bound achieved by Lebowitz and Penrose.
Polymer Gas Approach to N-Body Lattice Systems
A. Procacci, B. Scoppola
We give a simple proof, based only on combinatorial arguments, of the Kotecký–Preiss condition for the convergence of the cluster expansion. Then we consider spin systems with long-range N-body…
