标题： Semi-infinite throats at finite temperature and static solutions in exactly solvable models of 2d dilaton gravity

摘要： 发现是在有限温度下二维稀疏引力的精确可解模型中的静态解的一般形式。 我们揭示了存在处处正则解的可能性，包括黑洞、半无限喉部和星状结构。 特别是，我们考虑了具有半无限喉部的Bose-Parker-Peleg（BPP）模型，并在有限温度下对其进行分析。 我们还提出了BPP模型的推广，在这种推广中，半无限喉部的出现具有普遍性，不需要对解的参数进行特殊的微调。 显示英文摘要

摘要： Found is a general form of static solutions in exactly solvable models of 2d dilaton gravity at finite temperature. We reveal a possibility for the existence of everywhere regular solutions including black holes, semi-infinite throats and star-like configurations. In particular, we consider the Bose-Parker-Peleg (BPP) model which possesses a semi-infinite throat and analyze it at finite temperature. We also suggest generalization of the BPP model in which the appearance of semi-infinite throat has a generic character and does not need special fine tuning between parameters of the solution.
