Accelerately Expanding Cosmologies in f(R,Φ,X) Theory

In this study, beginning and today expansion of universe are viewed in f(R,Φ,X) gravity. Field equations their solutions Friedmann-Lemaître-Robertson-Walker cosmologies with perfect fluid obtained by considering f(R,Φ,X)=f_0 R+f_1 X^q-V(Φ) model. Validity both gravity model for non-static space-time geometries is discussed making use the matter dynamics results such as pressure energy density. It seen that all taking into account early late period expansion, f function a constant. This indicates first-order dependent Ricci scalar. When considered together, it understood could be reduced to Λ-CDM f(R) limits Φ→0 X→0. The fact agree expected situations supports. So, theory consistent
