共形引力的真空静态虫洞

Static wormholes in vacuum for conformal gravity

Julio Oliva, David Tempo, Ricardo Troncoso

摘要:

本文给出了真空中共形引力的静态球对称虫洞解,该解具有一个单一的积分常数,它决定了连接两个常曲率静态均匀宇宙的颈的大小。时间在颈部的每一侧以不同的速率运行,并且取决于参数的值,虫洞只能在一侧发展宇宙视界。结果表明,虫洞对应于不同爱因斯坦时空的匹配,通过不当的保角变换。

英文摘要:

A static spherically symmetric wormhole solution for conformal gravity in vacuum is found. The solution possesses a single integration constant which determines the size of the neck connecting two static homogeneous universes of constant spatial curvature. Time runs at different rates on each side of the neck, and depending on the value of the parameter, the wormhole can develop a cosmological horizon only at one side. It is shown that the wormholes correspond to the matching of different Einstein spacetimes by means of improper conformal transformations.
