Abstract Our primary objective in this paper is to analyze structure scalars against the background of f ( G , T ) gravity. The entire arrangement of conditions executing the structure and the development of self gravitating spherically symmetric dissipative fluids with anisotropic stresses, described as far as structure scalars (scalar functions) are obtained from the orthogonal splitting of the Riemann tensor, with regards to f ( G , T ) gravity. The physical behavior of structure scalars have been demonstrated for radiating matter by choosing the bivariate f ( G , T ) function in f 1 ( G ) + f 2 ( T ) form. These scalars are also analyzed by using constants G and T for dust cloud. It is concluded that evolutionary stages for relativistic celestial bodies can be examined by using modified scalar functions.

f(G,T)重力与结构标量

摘要 本文的主要目的是在 f ( G , T ) 重力背景下分析结构标量。执行结构的整个条件排列和具有各向异性应力的自引力球对称耗散流体的发展，就结构标量（标量函数）而言，是从黎曼张量的正交分裂中获得的，关于 f ( G , T) 重力。通过选择 f 1 ( G ) + f 2 ( T ) 形式的二元 f ( G , T ) 函数，结构标量的物理行为已被证明用于辐射物质。这些标量也通过使用尘埃云的常数 G 和 T 进行分析。结论是，相对论天体的进化阶段可以通过使用修正的标量函数来检查。
