Modave Lecture notes: Introduction to Exceptional Field Theory
AI总结:
本讲义系统介绍 Exceptional Field Theory,从 Kaluza-Klein 约化、超引力与弦对偶引出 E_{d(d)} 对称,阐述 E_{7(7)}-ExFT 等构造及其在一致截断中的应用。
摘要:
这些讲义基于在第十九届 Modave 数学物理学校所作的讲座,介绍 Exceptional Field Theory(例外场论)。内容涵盖环面上的标准 Kaluza-Klein 约化,并应用于超引力;回顾 IIA/IIB 型超引力以及十一维超引力的作用量。我们从弦对偶的视角说明隐藏对称群 E_{d(d)} 出现的动因,探讨 E_{7(7)}-ExFT 的构造与性质,并回顾 3≤d≤8 时的其他 E_{d(d)}-ExFT 以及双场论。讲义最后介绍 ExFT 在一致截断中的若干应用。
英文摘要:
These notes are based on lectures given at the XIX Modave School on Mathematical Physics and present an introduction to Exceptional Field Theory. We cover the standard Kaluza-Klein reductions on tori, with applications to supergravity. We review the supergravity action of type IIA/IIB and eleven-dimensional supergravities. We motivate the appearance of the hidden symmetry groups $\mathrm{E}_{d(d)}$ through the lens of string dualities. We explore the construction and properties of $\mathrm{E}_{7(7)}$-ExFT and review other $\mathrm{E}_{d(d)}$-ExFT for $3\leq d\leq 8$, as well as double field theories. These notes conclude with some applications of ExFT to consistent truncations.
