在共形规范中可以研究共形场理论与二维引力的耦合。作为应用，简单地导出了Knizhnik、Polyakov和Zamolodchikov关于共形场标度维的结果。证明了他们关于弦的磁化率指数γ的猜想，并将其推广到任意亏格曲面。这一结果与随机晶格模型的精确结果一致。
The coupling of conformal field theories to 2-d gravity may be studied in the conformal gauge. As an application, the results of Knizhnik, Polyakov and Zamolodchikov for the scaling dimensions of conformal fields are derived in a simple way. Their conjecture for the susceptibility exponent γ of strings is proven and extended to arbitrary genus surfaces. The result agrees with exact results from random lattice models.
