Modeling through the cubic parametrization of the deceleration parameter in f(R,Lm) gravity with observational constraints

In this paper, we investigate Friedmann Robertson Walker (FRW) space time filled with a perfect fluid in f(R,Lm) modified theory framework formulated by Harko and Lobo (2010), where R is the Ricci scalar curvature, Lm is the ideal fluid's Lagrangian. Two specific non-linear f(R,Lm) functional forms...
