标题： Magnetic Wormholes and Vertex Operators

摘要： 我们考虑了 $2+1$ 欧几里得维度中的虫洞解。 引入了一种对偶变换，用于从古普塔、休斯、普雷斯凯尔和怀斯的磁性虫洞作用量推导出一个新的作用量。 经典解被给出。 相应的虫洞顶点算符被推导出来。 在虫洞背景下考虑了共形耦合标量和旋量，并计算了顶点算符。 （将发表于《Phys. Rev. D15》） 显示英文摘要

摘要： We consider wormhole solutions in $2+1$ Euclidean dimensions. A duality transformation is introduced to derive a new action from magnetic wormhole action of Gupta, Hughes, Preskill and Wise. The classical solution is presented. The vertex operators corresponding to the wormhole are derived. Conformally coupled scalars and spinors are considered in the wormhole background and the vertex operators are computed. ( To be published in Phys. Rev. D15)
