Abstract: We present the analytical approach to scalar field theory on the fuzzy spherewhich has been developed in arXiv:0706.2493 hep-th. This approach is based onconsidering a perturbative expansion of the kinetic term in the partitionfunction. After truncating this expansion at second order, one arrives at amultitrace matrix model, which allows for an application of the saddle-pointmethod. The results are in agreement with the numerical findings in theliterature.
