摘要
本文研究了1+1维O(3)非线性σ-模型的哈密顿正则系统,证明了若对系统作一适当的正则变换,该模型中的拓扑项即可自行消失.文章对该结果的意义作了进一步的讨论.
The canonical system of O(3) nonlinear sigma model in 1+1 dimensions is studied in this paper. It is shown that the topological term in the model will disappear under a suitable canonical transformation for the system. The significance of this result is discussed.
