论文摘要
二维差异形态对称性可以通过众所周知的Virasoro代数代数描述保形对称性描述。利用此扩展，本说明解释了为什么不应将出现在天体全息图中的保形对称性扩展到差异形态对称性，这可能是几位作者提出的。此处介绍的二维差异代数的描述可能对其他目的有用。
Two-dimensional diffeomorphism symmetry can be described by an operator algebra extension of the well-known Virasoro algebra description of conformal symmetry. Utilizing this extension, this note explains why the conformal symmetry that appears in celestial holography should not be extended to diffeomorphism symmetry, a possibility that several authors have proposed. The description of the two-dimensional diffeomorphism algebra presented here might be useful for other purposes.
