Abstract
A quantitative estimate of the role of quantum fluctuations is given a t zero and finite temperatures within the one-loop approximation aroun d the antiferromagnetic and dimer saddle points. Our results include t he constraint of single occupancy of sites, also for thermodynamical q uantities.
