Request for edit summary
When editing an article on Wikipedia there is a small field labeled "Edit summary" under the main edit-box. It looks like this: The text written here will appear on the Recent changes page, in the page revision history, on the diff page, and in the watchlists of users who are watching that article. See m:Help:Edit summary for full information on this feature.

Filling in the edit summary field greatly helps your fellow contributors in understanding what you changed, so please always fill in the edit summary field, especially for big edits or when you are making subtle but important changes, like changing dates or numbers. Thank you. – Oleg Alexandrov (talk) 15:45, 2 November 2006 (UTC)

TeX issues
Hello. Please note that in TeX, you don't need to write
 * $$Z(\beta) = <\exp(-\beta E)>,\,$$
 * $$Z(\beta) = <\exp(-\beta E)>,\,$$

since instead you can write
 * $$Z(\beta) = \langle\exp(-\beta E)\rangle.\,$$
 * $$Z(\beta) = \langle\exp(-\beta E)\rangle.\,$$

Partition function
Hello BahramH. Your new subsection Cumulant tells a little about the partition function, but not about its relation to cumulant generating function. Bo Jacoby (talk) 21:10, 4 September 2008 (UTC).

Thanks, you're right. I have to add the cumulant expansion of the free energy as a perturbation technique. 9 september 2008.

Hamilton-Jacobi Equation
Thanks for your addition to this page, which I gather comes in part from your recent paper in AmJPhys. Two issues/questions:

1) Your statement "[t]he above duality is very general and applies to all systems that derive from a variational principle" is very broad and far-reaching, and as such needs a reference to support it. Could you please provide one?

2) Here (and also on the specific Wikipedia page on this topic) the action $$S$$ is referred to as Hamilton's principal function, while the Hamilton's characteristic function (via the abbreviated action) is the term used to describe the solution to the static HJE. In your paper, you refer to this solution as Hamilton's principal function. Could you perhaps clear up this possible conflict? (or correct me if I'm finding a conflict that isn't there?)
