广义DBI的降维

Dimensional Reduction of the Generalized DBI

Jun-Kai Ho, Chen-Te Ma

摘要:

研究了广义Dirac-Born-Infeld(DBI)作用,它描述了一个以($q$ +1)-形式背景的$p$-膜为结尾的$q$-膜.该作用在交换和非交换条件下具有等价的描述,可以从广义度量和Nambu-西格玛模型中得到证明。本文主要讨论了在平坦时空、恒定反对称背景和规范势为零的情况下,在平坦时空和恒定反对称背景下,广义DBI在无质量水平上的降维问题。在$q=2$的情况下,我们可以通过降维得到DBI理论。我们还试图通过包括一种形式的规范势来扩展这个理论。

英文摘要:

We study the generalized Dirac-Born-Infeld (DBI) action, which describes a $q$-brane ending on a $p$-brane with a ($q$+1)-form background. This action has the equivalent descriptions in commutative and non-commutative settings, which can be shown from the generalized metric and Nambu-Sigma model. We mainly discuss the dimensional reduction of the generalized DBI at the massless level on the flat spacetime and constant antisymmetric background in the case of flat spacetime, constant antisymmetric background and the gauge potential vanishes for all time-like components. In the case of $q=2$, we can do the dimensional reduction to get the DBI theory. We also try to extend this theory by including a one-form gauge potential.
