超膜的三代数与超弦的二代数

Three-algebra for supermembrane and two-algebra for superstring

Kanghoon Lee, Jeong-Hyuck Park

摘要:

虽然弦理论或杨米尔斯理论是基于李代数或二代数结构,但最近的研究表明M理论可能需要更高的三代数结构。在这里,我们构造了一个十一维超膜的协变作用量,它在整体超对称性,局域费米对称性和世界体积同态下是不变的。我们的行动是经典的壳相当于著名的伯格肖夫-塞兹金-汤森行动。然而,新颖之处在于,我们真正用Nambu三括号来拼写动作:所有的导数都通过Nambu括号出现,因此它体现了三代数结构。进一步地,我们的作用量的双维约化直接给出了具有双代数特征的IIA型弦作用量。应用同样的方法,我们还构造了IIB超弦的协变作用量,直接导出了IKKT矩阵模型。

英文摘要:

While string or Yang-Mills theories are based on Lie algebra or two-algebra structure, recent studies indicate that M-theory may require a one higher, three-algebra structure. Here we construct a covariant action for a supermembrane in eleven dimensions, which is invariant under global supersymmetry, local fermionic symmetry and worldvolume diffeomorphism. Our action is classically on-shell equivalent to the celebrated Bergshoeff-Sezgin-Townsend action. However, the novelty is that we spell the action genuinely in terms of Nambu three-brackets: All the derivatives appear through Nambu brackets and hence it manifests the three-algebra structure. Further the double dimensional reduction of our action gives straightforwardly to a type IIA string action featuring two-algebra. Applying the same method, we also construct a covariant action for type IIB superstring, leading directly to the IKKT matrix model.
