Abstract
We extend the proof by Osterwalder and Seiler of reflection positivity of lattice gauge theories with fermions to the case in which the reflection is performed with respect to planes containing sites. Our proof applies to all observables and relies on the particular structure of the Wilson action. This assures the positivity of the correlation functions 〈θ(F)F〉 for any gauge invariant function F and at all euclidean time separations as of interest in Monte Carlo calculations. © 1987 Springer-Verlag.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
