| The partition function of 3d N=2 superconformal theories on the 3-sphere can be computed exactly by localization methods. I will explain some sublteties associated to that important result. As a by-product, this analysis establishes the so-called F-maximization principle for N=2 SCFTs in 3d: the exact superconformal R-charge maximizes the 3-sphere free energy F=-log Z. | |||
