无荷荷、正则球对称解和Einstein-Born-Infeld理论

Charge without charge, regular spherically symmetric solutions and the Einstein-Born-Infeld theory

D. J. Cirilo Lombardo

摘要:

本文从时空几何和电磁结构的角度继续研究了JMP 46,042501(2005)中Einstein-Born-Infeld理论中的正则静态球对称时空。给出了该时空的能量条件、测地完备性和视界的主要特征。本文提出并分析了一种新的静态球对称双子解,它具有与我们以前工作中的规则纯电和纯磁情形相似的良好性质。此外,规避的“不去”定理的版本声称不存在规则的电黑洞和其他电磁静态球形配置与规则的中心是通过处理一个更一般的陈述的问题。

英文摘要:

The aim of this paper is to continue the research of JMP 46, 042501 (2005) of regular static spherically symmetric spacetimes in Einstein-Born-Infeld theories from the point of view of the spacetime geometry and the electromagnetic structure. The energy conditions, geodesic completeness and the main features of the horizons of this spacetime are explicitly shown. A new static spherically symmetric dyonic solution in Einstein-Born-Infeld theory with similar good properties as in the regular pure electric and magnetic cases of our previous work, is presented and analyzed. Also, the circumvention of a version of "no go" theorem claiming the non existence of regular electric black holes and other electromagnetic static spherically configurations with regular center is explained by dealing with a more general statement of the problem.
