最近，由复合算符、有效弦模型和ADS/CFT对应引起的2D量子场理论的变形之间出现了令人惊讶的联系。本文的目的是讨论与二维相互作用场理论的形变有关的各种经典问题。我们特别注意了SIN(H)-Gordon模型，对于该模型，我们能够构造-形变Lax对。我们认为，Lax对公式是在可积模型框架内对这种变形进行更满意的几何解释的第一个基本步骤。
Surprising links between the deformation of 2D quantum field theories induced by the compositeoperator, effective string models and the AdS/CFT correspondence, have recently emerged. The purpose of this article is to discuss various classical aspects related to the deformation of 2D interacting field theories. Special attention is given to the sin (h)-Gordon model, for which we were able to construct the-deformed Lax pair. We consider the Lax pair formulation to be the first essential step toward a more satisfactory geometrical interpretation of this deformation within the integrable model framework.
