摘要：

The CP(N-1) model in three Euclidean dimensions is studied in the presence of a Chern-Simons term using the 1/N expansion. The beta-function for the statistics parameter-theta is found to be zero to order 1/N in the unbroken phase by an explicit calculation. It is argued to be zero to all orders. Some remarks on the theta-dependence of the critical exponents are also made.
