论文摘要
在本文中，我们继续在$ f（g）$引力理论中继续进行Herrera \ emph {et al。} \ cite {herrera20dynamical}的工作。为此，在考虑的情况下，考虑了局部各向异性压力以及能量密度的球形对称流体。扰动方案施加在修改的场方程和动力学方程上。崩溃方程是从这些扰动的方程式中设计出来的，这些方程刺激了在牛顿和牛顿后约束下披露不稳定区。结束了结论，结论是由绝热指数$γ$解释的动力不稳定性，该$γ$依赖于各向异性压力，能量密度和由于$ f（g）$ raverity而导致的黑暗源项。
In this paper, we have continued the work of Herrera \emph{et al.} \cite{herrera2012dynamical} in $f(G)$ gravitational theory. For this purpose, a spherically symmetric fluid exhibiting locally anisotropic pressure along with the energy density, is taken under consideration. The perturbation scheme is imposed on modified field equations and the dynamical equations. The collapse equation is devised from these perturbed equations which stimulates to disclose the instability zone under both Newtonian and post-Newtonian constraints. It is wrapped up by concluding that dynamical instability is interpreted by the adiabatic index $Γ$ which relies on the anisotropic pressure, energy density and the dark source terms due to $f(G)$ gravity.
