In this paper, we studied the statistical behavior of anyons with isospin degrees of freedom, in which the fluctuation of isospin degrees of freedom satisfies the O(3) nonlinear σ model. Under the mean field treatment, this model is in somewhat equivalent to the doped or frustrated Heisenberg antiferromagnetic (AFM) model. We also studied the relation between the statistical field A μ , and Skyrmion current B μ . Finally, we set up the relation between flux states and spinon statistics, and the conditions of Bose condensation of holons. In particular, for π -flux state of A μ , the spinons are bosons, the holons satisfy 2/3 fractional statistics.
