The noncommutative self-dual φ3 model in six dimensions is quantized
and essentially solved, by mapping it to the Kontsevich model.
The model is shown to be renormalizable and asymptotically free, and
solvable genus by genus. It requires both wavefunction and coupling
constant renormalization. The exact (“all-order”) renormalization of the
bare parameters is determined explicitly, which turns out to depend on
the genus 0 sector only. The running coupling constant is also computed
exactly, which decreases more rapidly than predicted by the 1-loop
beta-function. A phase transition to an unstable phase is found.
