how does such an analytic continuation relate stat mech to qft? does anyone know?
thank-you!

The relationship between QFT and statistical mechanics arises because after Wick rotation the 4-space has a Euclidean metric, just like the three space in problems in statistical mechanics. Therefore oftentimes expressions from QFT are formally identical to those in statistics. This has nothing to do with the spin-statistics theorem.

Would it be worth mentioning that neither the Minkowsi metric is a metric but rather a pseudometric nor that the resulting formula does comply, in a strict sense, with any norm on the complex vector space and thus any theorem valid for a metric or norm cannot be used whitout checking if it is still valid in this deviated case. 84.160.211.96 10:20, 7 January 2006 (UTC)
