Existence of Energy Density Homogeneity for Radiating Spheres in f (G, T ) Gravity
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.
