摘要
The purpose of this paper is to investigate the definition of complexity for static anisotropic cylindrical objects in the background of f (G, T) gravity, where G and T stand for Gauss-Bonnet term and trace of the energy-momentum tensor, respectively. We develop the modified field equations, Tolman-Oppenheimer-Volkoff equation, mass distribution and structure scalars. The complexity is calculated from the splitting of the Riemann tensor in terms of a complexity factor which is associated with the physical characteristics (anisotropic pressure, inhomogeneous energy density) of the system. The zero complexity condition is derived as a constraint to estimate the behaviour of two compact objects corresponding to Gokhroo and Mehra ansatz and polytropic equation of state. We conclude that the addition of f (G, T) terms contribute to the increment in the complexity of the system.
