抽象。我们在两个不同的域中研究了二维时空中的sine-Gordon模型。对于β > 8π和弱耦合的情况,我们引入了紫外截止,并研究了其红外行为。重整化群分析表明,该模型在红外波段是渐近自由的。在β < 8π和弱耦合的情况下,我们引入了红外截止,并研究了其紫外行为。重整化群分析表明,该模型在紫外区是渐近自由的。
Abstract. We study the sine-Gordon model in two dimensional space time in two different domains. For β > 8π and weak coupling, we introduce an ultraviolet cutoff and study the infrared behavior. A renormalization group analysis shows that the model is asymptotically free in the infrared. For β < 8π and weak coupling, we introduce an infrared cutoff and study the ultraviolet behavior. A renormalization group analysis shows that the model is asymptotically free in the ultraviolet.
