Add to ORKGWe present a renormalization group analysis of a two dimensional Coulomb gas with internal degrees of freedom. The specific model considered has a global O(3) internal symmetry. The behavior of this system in the low temperature region is found to differ appreciably from that of the XY model. © 1981
