量子反铁磁体与O（3）非线性σ模型相等性

THE EQUALITY OF THE MODELS OF QUANTUM ANTIFERROMAGNETS AND O(3) NON LINEAR σ

应用量子作用角变量等方法证明了量子反铁磁体模型与Ｏ（３）非线性σ模型有相等性，并由此相等性。

Using such method as the angle variable of quantum function, the author of this thesis proves that the models of quantum antiferromagnets and O(3) non linear σ are equal and from this equality, draws several important inferences about the model of quantum antiferromagnets.
