摘要
本文讨论了O(3)非线性σ模型在对偶变换下的对称性,探讨了生成函数变换的根源;证实该模型中具有无穷保形对称性;得到了基本场的无穷维李代数结构及两种代数间的半直积关系;最后给出了相应的Bianchi-Backlund变换.
The symmetry of O(3) non-linear sigma model under a dual transformation is discussed and the origin of the transformation of generating functions is explored; Existence of the infinite dimensional conformal symmetries is confirmed. We obtain the infinite dimensional Lie algebraic structure of the basic fields and the semi-product algebraic relation of the two kinds of algebra. The corresponding Bianchi-Backlund transformations are given.
