## Abstract

Noncommutative U(1) gauge theory in 4−dimensions is shown to be equivalent in some scaling limit to an ordinary non-linear sigma model in 2−dimensions . The model in this regime is solvable and the corresponding exact beta function is found. We also show that classical U(n) gauge theory on R^(d−2) × R_θ^2 can be approximated by a sequence of ordinary (d − 2)−dimensional Georgi-Glashow models with gauge groups U(n(L + 1)) where L + 1 is the matrix size of the regularized noncommutative plane R_θ^2.
