Unimodular f(G, T) gravity

In this study, unimodular f(G,T) gravity is proposed as an alternative theory of gravity. Field equations of unimodular f(G,T) gravity are suggested. The field equation and their solutions are obtained for exponential expansion and power-law expansion models. Energy conditions of unimodular f(G,T) gravity are defined by using Raychaudhuri equations. Energy conditions for exponential expansion and power-law expansion models are investigated. Hubble parameter and deceleration parameter are calculated by considering power-law expansion model and obtained solutions. It has been shown that both deceleration parameter and Hubble parameter are compatible with the current observational data.
