论文摘要
在论文中，我们通过一个充满无限电导率的冷等离子体的时空研究了一般相对论的光的传播。我们使用基于Synge方法的几何光学元件。作为主要结果，我们提供了一种计算从尖端源发出的辐射光谱通量的公式。该公式采用连接向量，这些向量是通过沿连接源和观察事件的参考射线集成射线偏差方程来获得的。作为副产品，我们通过包含等离子体，相互关联的角度距离和亮度距离来制定Etherington的互惠定理。我们还通过连接向量讨论了liouville定理及其表述。
In the paper we study propagation of light in general relativity through a spacetime filled with cold plasma with infinite conductivity. We use the geometric optics based on Synge's approach. As the main result we provide a formula for calculation of spectral flux of radiation emitted from a pointlike source. The formula employs connecting vectors that are obtained by integrating the ray deviation equation along the reference ray connecting the source and observation event. As a byproduct we formulate Etherington's reciprocity theorem with the inclusion of plasma, interrelating angular size distance and luminosity distance. We also discuss the Liouville theorem and its formulation in terms of connecting vectors.
