论文摘要
我们在爱因斯坦（Maxwell）系统中对带电的黑洞和虫洞溶液进行了分类并研究了一个无质量的真实标量场。在{Bronnikov等，1999;}黑洞和蠕虫孔中存在一个负量表，在标量场中存在一个负量的理论中，有带电的黑洞可能存在。 Using a conformal transformation, the static, spherically symmetric possible structures in the minimal coupled system are described.除了虫洞和赤裸裸的奇异点外，只有一类限制的黑洞，展现出无限表面和时型中心奇异性的地平线。爱因斯坦框架中定义的黑洞和虫洞与非最小耦合原始框架具有一些特异性，这在文本中进行了讨论。
We classified and studied the charged black hole and wormhole solutions in the Einstein--Maxwell system in the presence of a massless, real scalar field. The possible existence of charged black holes in general scalar--tensor theories was studied in {Bronnikov et al, 1999;} black holes and wormholes exist for a negative kinetic term for the scalar field. Using a conformal transformation, the static, spherically symmetric possible structures in the minimal coupled system are described. Besides wormholes and naked singularities, only a restricted class of black hole exists, exhibiting a horizon with an infinite surface and a timelike central singularity. The black holes and wormholes defined in the Einstein frame have some specificities with respect to the non-minimal coupling original frame, which are discussed in the text.
