我们重新审视二维洛伦兹共形场论使用的形式主义以前开发的正弦平方变形的欧几里得共形场论的研究。我们构造了三种类型的Virasoro代数。其中一个复制了Lüscher和Mack的结果，而另一种类型在中心电荷项中表现出发散。第三个导致一个连续的频谱，不包含封闭的系统中的类时曲线。
We reexamine two-dimensional Lorentzian conformal field theory using the formalism previously developed in a study of sine-square deformation of Euclidean conformal field theory. We construct three types of Virasoro algebra. One of them reproduces the result by Lüscher and Mack, while another type exhibits divergence in the central charge term. The third leads to a continuous spectrum and contains no closed time-like curve in the system.
