摘要
我们在由非阿贝尔对偶变换联系的二维西格玛模型中研究耦合常数重整化。就此而言，我们证明在微扰论的单圈阶，插值于SU(2)主模型与O(3)西格玛模型之间的一参数族模型的了对偶模型展现出与原始模型相同的行为。对于O(3)模型也研究了双圈等价性，并发现其破缺，正如已然熟知的主模型例子一样。

备注
As a result of the collaboration of new authors the previously overlooked gauge contribution is inserted into eq.(43) changing not so much the formulae as part of the conclusion: for the models considered non Abelian duality is OK in one loop
