Abstract EN
The study of energy conditions has many significant applications in general relativistic and cosmological contexts.
This paper explores the energy conditions in the framework of the most general scalar-tensor theory with field equations involving second-order derivatives.
For this purpose, we use flat FRW universe model with perfect fluid matter contents.
By taking power law ansatz for scalar field, we discuss the strong, weak, null, and dominant energy conditions in terms of deceleration, jerk, and snap parameters.
Some particular cases of this theory like k-essence model, modified gravity theories and so forth.
are analyzed with the help of the derived energy conditions, and the possible constraints on the free parameters of the presented models are determined.
