论文摘要
在这封信中，我们概括了基于B迁移和一系列非等级方向上的正式Abelian T二维的非阿布尔T偶对偶的程序。这是由C档组成的，然后是正式的U-二元转换或进行IIB部分。我们研究了该过程的限制和适用性，并发现仅当存在观众场时，它才能为SL（5）特殊Drinfeld代数提供超级强烈解决方案，这与文献中已知的示例一致。
In this letter we generalised the procedure of non-abelian T-duality based on a B-shift and a sequence of formal abelian T-dualities in non-isometric directions to 11-dimensional backgrounds. This consists of a C-shift followed by either a formal U-duality transformation or taking a IIB section. We investigate restrictions and applicability of the procedure and find that it can provide supergravity solutions for the SL(5) exceptional Drinfeld algebra only when a spectator field is present, which is consistent with examples known in the literature.
