关于11维背景的非交换U-对偶

On non-abelian U-duality of 11D backgrounds

Edvard T. Musaev

摘要:

在这封信中,我们推广的程序的非阿贝尔T-对偶的基础上的B-移位和一系列的正式阿贝尔T-对偶在非等距方向的11维背景。这包括一个C-移位,然后是一个正式的U-对偶变换或取一个IIB截面。我们研究了该方法的局限性和适用性,发现只有当存在旁观者场时,它才能给出SL(5)例外Drinfeld代数的超引力解,这与文献中已知的例子是一致的.

英文摘要:

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.
