摘要：
In this paper, we consider the flat FriedmannLematreRobertson-Walker metric in the presence of perfect fluid models and extended f(R, G, T) gravity (where R is the Ricci scalar, G is the Gauss Bonnet invariant and T stands for trace of energy momentum tensor). In this context, we assume some specific realistic f(R, G, T) models configuration that could be used to explore the finite-time future singularities that arise in late-time cosmic accelerating phases. In this scenario, we choose the most recent estimated values for the Hubble, deceleration, snap and jerk parameters to develop the viability and bounds on the models parameters induced by different energy conditions.
