Abstract

This work discusses the responsible quantities of the emergence inhomogeneity by taking locally anisotropic radiating fluid in f(G, T ) theory of gravity, where G is the Gauss-Bonnet term and T is the trace of stress-energy tensor. The temporal and radial change in mass function is observed with the help of modified version of Einstein’s field equations. To observe the dynamics of self-gravitating fluid, the dynamical equations and differential equations for conformal tensor are formulated, which help to understand the role of correction terms, Weyl curvature and fluid parameter in the energy-density irregularity. Different aspects of fluid are considered to meet the desired results.
f (G, T)重力下辐射球能量密度均匀性的存在性
本文以f(G, T)引力理论中的局部各向异性辐射流体为例,讨论了涌现非均匀性的责任量,其中G为高斯-博内项,T为应力-能量张量的轨迹。借助爱因斯坦场方程的修正版本,观察了质量函数的时间和径向变化。为了观察自重力流体的动力学,建立了共形张量的动力学方程和微分方程,有助于理解修正项、Weyl曲率和流体参数在能量密度不规则性中的作用。考虑流体的不同方面以满足期望的结果。
