Description

We study the compatibility between the BPST SU(2) instanton and the fuzzy four-sphere algebra. By using the projective module point of view as an intermediate step, we are able to identify a noncommutative solution of the matrix model equations of motion which minimally extends the SU(2) instanton solution on the classical sphere S4. We also propose to extend the non-trivial second Chern class with the five-dimensional noncommutative Chern-Simons term
