摘要
我们考虑了2+1维中带有Wess-Zumino-Witten项和拓扑流密度平方项的高阶导数CP(N)模型。我们使用路径积分方法中的辅助规范场表述来量子化该理论，并证明了扩展模型在大N极限下保持可重整性。我们发现，在非平凡紫外不动点处，大N有效作用量中动态诱导了Maxwell-Chern-Simons理论。还讨论了Chern-Simons项的量子化。

备注
8 pages, no figure, a minor change in abstract, added Comments on the quantization of the Chern-Simons term whose coefficient is also corrected, and some references are added. Some typos are corrected. Added a new paragraph checking the equivalence between (3) and (5), and a related reference
