Abstract
We show that the solitons of the SO(3) nonlinear sigma model in 2+1 di mensions, when coupled to gravitation with the gravitational Chern-Sim ons interaction, become anyons in the absence of the Hopf term. In par ticular we calculate the fractional statistical factor of the gravitat ing anyons, and prove that the gravitational Chern-Simons term itself can be interpreted as the Hopf term of the topological current of PI2 (S2).
