标题： Scalar waves in a wormhole topology

摘要： 平坦虫洞中的标量波动方程的全局单色解在2+1维和3+1维情况下得到。 这些解以包含柱面波函数和球面波函数的无穷级数形式出现，并通过多重散射方法进行阐明。 一些极限情况的显式解也得到了说明。 本文中呈现的结果是存在于允许闭合类时曲线的时空中的标量波动方程的解的实例。 显示英文摘要

摘要： Global monochromatic solutions of the scalar wave equation are obtained in flat wormholes of dimensions 2+1 and 3+1. The solutions are in the form of infinite series involving cylindirical and spherical wave functions and they are elucidated by the multiple scattering method. Explicit solutions for some limiting cases are illustrated as well. The results presented in this work constitute instances of solutions of the scalar wave equation in a spacetime admitting closed timelike curves.
