基于体标量场的$p$ -膜的几个新作用量

Several new actions of $p$-branes based on bulk scalar fields

Yi-Shi Duan, Zhen-Bin Cao

摘要:

一般来说,$p$ -膜在揭示弦/M-理论的非微扰结构方面发挥着核心作用。本文利用体标量场构造的拓扑张量流,首先给出了$p$ -膜的一些拓扑性质,然后重点讨论了$p$ -膜的几种新作用量的构造.我们表明,我们所构造的行动,可以减少到Nambu-Goto行动或其他一些简单的行动,都自然地定义在散装时空,保持完整的时空洛伦兹不变性,并满足自对偶条件。

英文摘要:

Generally, $p$-branes play central roles in revealing the nonperturbative structures of the string/M-theory. In this paper, through a topological tensor current constructed in terms of a bulk scalar field, we first show some topological properties of $p$-branes, and then mainly discuss the construction of several new actions of $p$-branes. We show that the actions we construct which can be reduced to the Nambu-Goto action or some other simple actions, are all defined naturally in the bulk spacetime, preserving the full spacetime Lorentz invariance and satisfying a self-dual condition.
