我们确定了典型的高能量本征态的二维共形场理论在有限的c和建立，在这种状态下的应力张量的相关函数是准确的热定义的标准正则系综。维h的典型状态被示出为典型的水平h/c后代。在AdS 3/CFT 2对应关系中，这种状态应该与整体黑洞进行比较。我们还讨论了热膨胀剂和那些计算在高能量初级状态之间的差异：后者是再现，而不是由一个广义吉布斯系综与极端值选择共轭的KdV电荷的化学势。
We identify typical high energy eigenstates in two-dimensional conformal field theories at finite c and establish that correlation functions of the stress tensor in such states are accurately thermal as defined by the standard canonical ensemble. Typical states of dimension h are shown to be typical level h/c descendants. In the AdS3/CFT2 correspondence, it is such states that should be compared to black holes in the bulk. We also discuss the discrepancy between thermal correlators and those computed in high energy primary states: the latter are reproduced instead by a generalized Gibbs ensemble with extreme values chosen for the chemical potentials conjugate to the KdV charges.
