论文摘要
我们在$ 2+1 $尺寸时空中构建了BMS代数扩展的免费场。除了超级翻译和超值脱离外，扩展还包含一组无限的超延伸。 我们还评论了试图将代数扩展到完整的共同组时出现的困难。
We construct a free field realization of an extension of the BMS algebra in $2+1$ dimensional space-time. Besides the supertranslations and superrotations, the extension contains an infinite set of superdilatations. We also comment the difficulties that appear when trying to extend the algebra to that of the full conformal group.
