除代数与超对称性II

Division Algebras and Supersymmetry II

John C. Baez, John Huerta

摘要:

从四个赋范除代数-实数、复数、四元数和八元数-出发,系统地给出了3维、4维、6维和10维Poincare李超代数上的3-上圈。一个相关的过程给出了一个4维、5维、7维和11维的Poincare李超代数上的4-上圈。一般来说,李超代数上的(n+1)-上圈产生一个“李n-超代数”:也就是说,粗略地说,一个n项链复形配备了一个括号,满足李超代数直到链同伦的公理。从而得到了Poincare超代数在3,4,6,10维上的Lie 2-超代数和Poincare超代数在4,5,7,11维上的Lie 3-超代数。正如Sati、Schreiber和Stasheff在高规范理论上的工作所示,Lie 2-超代数连接描述了弦的平行输运,而Lie 3-超代数连接描述了2-膜的平行输运。此外,在八元数情况下,这些联系简明地概括了10维和11维超引力中出现的场。

英文摘要:

Starting from the four normed division algebras - the real numbers, complex numbers, quaternions and octonions - a systematic procedure gives a 3-cocycle on the Poincare Lie superalgebra in dimensions 3, 4, 6 and 10. A related procedure gives a 4-cocycle on the Poincare Lie superalgebra in dimensions 4, 5, 7 and 11. In general, an (n+1)-cocycle on a Lie superalgebra yields a "Lie n-superalgebra": that is, roughly speaking, an n-term chain complex equipped with a bracket satisfying the axioms of a Lie superalgebra up to chain homotopy. We thus obtain Lie 2-superalgebras extending the Poincare superalgebra in dimensions 3, 4, 6, and 10, and Lie 3-superalgebras extending the Poincare superalgebra in dimensions 4, 5, 7 and 11. As shown in Sati, Schreiber and Stasheff's work on higher gauge theory, Lie 2-superalgebra connections describe the parallel transport of strings, while Lie 3-superalgebra connections describe the parallel transport of 2-branes. Moreover, in the octonionic case, these connections concisely summarize the fields appearing in 10- and 11-dimensional supergravity.
