Dynamical analysis of generalized f ( R , L ) theories

Dynamical analysis of generalized f ( R , L ) theories

In this work, we use a dynamical system approach to analyze the viability of f(R,L) candidates for dark energy. We compare these with nonminimal coupled f(R) theories and study the solutions for exponential and power-law forms in order to constrain the allowed range of model parameters.
