$f(R)$ -修正引力理论中的某些特殊虫洞解

Bikram Ghosh, Saugata Mitra, Subenoy Chakraborty

摘要:

本文讨论了具有各向异性物质场的$f(R)$ -修正引力理论中静态球对称虫洞解以及某些特殊的形函数选择。目前的工作可以被认为是一般形式主义在\cite{r15}寻找虫洞的解决方案的扩展。对于各向同性的物质分布,它已被证明虫洞解决方案是可能的零潮汐力,它修改的索赔\cite{r17}。最后,能量条件进行检查,它被发现,所有的能量条件都满足在一个特定的域与一个特定的选择的形状函数。

英文摘要:

The paper deals with the static spherically symmetric wormhole solutions in $f(R)$-modified gravity theory with anisotropic matter field and for some particular choices for the shape functions. The present work may be considered as an extension of the general formalism in \cite{r15} for finding wormhole solutions. For isotropic matter distribution it has been shown that wormhole solutions are possible for zero tidal force and it modifies the claim in \cite{r17}. Finally energy conditions are examined and it is found that all energy conditions are satisfied in a particular domain with a particular choice of the shape function.
