AI 中文摘要
在本研究中，我们旨在通过Carrollian框架建立AdS₃/BCFT₂对应关系的平直版本的基础。我们首先讨论近期发现的边界Carrollian共形代数（BCCA），即Carrollian BCFT的对称代数。我们通过选择合适的世界末端（EOW）膜，在平直时空的零无穷远处识别该代数，从本质上以及通过从其AdS对应物取平直极限，分析了该EOW膜的性质。我们还发现，受该EOW膜限制的平直时空的整体及渐近对称性，与BCCA的对称性完全一致。
英文摘要
In this work we aim to lay the foundation of flat version of AdS$_3$/BCFT$_2$ correspondence through Carrollian framework. We begin with discussing the recently discovered Boundary Carrollian Conformal Algebra (BCCA), the symmetry algebra of Carrollian BCFT. We identify this algebra at the null infinity of flat spacetime with appropriate choice of the end-of-the-world (EOW) brane. The properties of this EOW brane have been analysed both intrinsically and by taking flat limit from its AdS counterpart. We also find that the global as well as asymptotic symmetries of flat spacetime restricted by this EOW brane coincide exactly with the symmetries of BCCA.
