半极大扩充Drinfel'd代数

Half-maximal Extended Drinfel'd Algebras

Yuho Sakatani

摘要:

扩展Drinfel'd代数(ExDA)是弦论低能有效理论中非Abel对偶的基础对称。极大超引力中的非Abel U-对偶已经得到了很好的研究,但是半极大超引力中的非Abel对偶还没有得到研究。本文构造了$d\geq 4$中半极大超引力的ExDA.在这些理论中,我们还发现了齐次经典Yang-Baxter方程的一个推广。

英文摘要:

Extended Drinfel'd algebra (ExDA) is the underlying symmetry of non-Abelian duality in the low-energy effective theory of string theory. Non-Abelian U-dualities in maximal supergravities have been studied well, but there has been no study on non-Abelian dualities in half-maximal supergravities. In this paper, we construct the ExDA for half-maximal supergravities in $d\geq 4$. We also find an extension of the homogeneous classical Yang-Baxter equation in these theories.
