在具有圆锥型线奇点的欧几里得空间中，我们确定了带电大质量标量场与穿过线奇点的磁通量相互作用的格林函数。我们给出了格林函数的积分表达式和在点源附近的局部形式，其中它是欧几里德空间中通常的格林函数与正则项的和。作为应用，我们导出了任意磁通量在无质量情况下的真空能量动量张量。
In an Euclidean space with a conical-type line singularity, we determine the Green's function for a charged massive scalar field interacting with a magnetic flux running through the line singularity. We give an integral expression of the Green's function and a local form in the neighbourhood of the point source, where it is the sum of the usual Green's function in Euclidean space and a regular term. As an application, we derive the vacuum energy-momentum tensor in the massless case for an arbitrary magnetic flux.
