标题： On maximal analytical extension of the Vaidya metric

摘要： 经典的Vaidya度规在质量函数为线性的情况下被转换为特殊的对角坐标，这使得处理变得相当容易。 使用这些坐标，我们详细研究了具有黑洞质量线性增长的Vaidya度规的最大解析延拓，并为不同的具体案例构建了相应的Carter-Penrose图。 推导出的全局几何结构似乎也适用于Vaidya度规中黑洞质量的更一般行为。 显示英文摘要

摘要： The classical Vaidya metric is transformed to the special diagonal coordinates in the case of the linear mass function allowing rather easy treatment. Using these coordinates, we elaborate the maximum analytic extension of the Vaidya metric with a linear growth of the black hole mass and construct the corresponding Carter-Penrose diagrams for different specific cases. The derived global geometry seemingly is valid also for a more general behavior of the black hole mass in the Vaidya metric.
