论文摘要
在本文中，我们分析了Bronnikov虫洞的整体结构，这是爱因斯坦重力中最通用的球形对称性和静态溶液，该溶液耦合到免费的无质量幻影标量。然后，我们引入标量电位，并构建一类精确的解决方案，这些解决方案可以看作是Bronnikov虫洞的概括。我们研究全球结构并对这些新虫洞的参数进行分类。对于合适的参数，有些是常规的黑洞，在事件范围内有弹跳的DE Sitter时空。
In this paper, we analyse the global structure of the Bronnikov wormhole, which is the most general spherically-symmetric and static solution in Einstein gravity coupled to a free massless phantom scalar. We then introduce a scalar potential and construct a large class of exact solutions that can be viewed as generalizations of the Bronnikov wormhole. We study the global structure and classify the parameters of these new wormholes. For suitable parameters, some are regular black holes with a bouncing de Sitter spacetime inside the event horizon.
