摘要

重新讨论了势理论中的一个经典问题（长刚性管内的点源）。它有大量的文献，但它的解决方案并不简单：标准方法导致发散积分或需要丢弃无限常数。我们证明了使用经典方法可以严格地解决这个问题。

On Green’s function for Laplace’s equation in a rigid tube

A classical problem from potential theory (a point source inside a long rigid tube) is revisited. It has an extensive literature but its resolution is not straightforward: standard approaches lead to divergent integrals or require the discarding of infinite constants. We show that the problem can be solved rigorously using classical methods.
