川口拉格朗日公式在弦论中的应用

Application of Kawaguchi Lagrangian formulation to string theory

Ryoko Yahagi, Akio Sugamoto

摘要:

提出了弦-标对偶。Hosotani和A. Sugamoto在川口拉格朗日公式的背景下重新审查。这个公式的特点是场和参数的无差别性质。因此,甚至可以在字段和参数之间交换角色。这样,上面的对偶性就很容易证明了。作为费米子场与参数交换的一个例子,研究了在超弦模型中用Neveu-Schwarz-Ramond(NSR)费米子的第九分量代替二维超空间中Grassmann参数的作用.紧化也在这个模型中进行了讨论。

英文摘要:

String-scalar duality proposed by Y. Hosotani and membrane-scalar duality by A. Sugamoto are reexamined in the context of Kawaguchi Lagrangian formulation. The characteristic feature of this formulation is the indifferent nature of fields and parameters. Therefore even the exchange of roles between fields and parameters is possible. In this manner, dualities above can be proved easily. Between Kawaguchi metrics of the dually related theories, a simple relation is found. As an example of the exchange between fermionic fields and parameters, a replacement of the role of Grassmann parameters of the 2-dimensional superspace by the 9th component of Neveu-Schwarz-Ramond (NSR) fermions is studied in superstring model. Compactification is also discussed in this model.
