From a string theory point of view the most natural gauge action on the fuzzy sphere SL2 is the Alekseev–Recknagel–Schomerus action which is a particular combination of the Yang–Mills action and the Chern–Simons-like term. The differential calculus on the fuzzy sphere is 3-dimensional and thus the field content of this model consists of a 2-dimensional gauge field together with a scalar fluctuation...
