Fuzzy torus in matrix model Original Research Article

We have calculated the free energy up to two loop to compare image with image in IIB matrix model. It turns out that image has smaller free energy than image. We have also discussed the generation of the gauge group by considering k-coincident fuzzy tori and found that in this case image gauge group is favored. This means that if the true vacuum is four-dimensional, it is not a simple fuzzy space considered here.
