Talk:Cluster expansion

Variable Explanation
I don't know off-hand how to assign the variables shown in the expression for Z_0, but the whole section becomes rather obscure without knowing what some of these things are. For example, what is h? Planck's constant? — Preceding unsigned comment added by 73.158.136.82 (talk) 00:08, 31 October 2016 (UTC)

Statement moved to talk
I have removed the statement:
 * It is only defined for field theories on a lattice, and not field theories on a continuum.

from the article, since I doubt it. The article seems to be mostly about the Mayer cluster expansion in classical physics, and all the textbooks I looked at about it (three) treat space as a continuum. Cardamon (talk) 20:59, 12 July 2011 (UTC)

check formulae
Most of the sum and product expressions don't make sense. Indices appear twice, limits are undefined. — Preceding unsigned comment added by 50.79.36.249 (talk) 18:27, 15 April 2012 (UTC)
