Cosmologies in f(R, _{ m }) theory with nonminimal coupling between geometry and matter
Abstract
Among the recent extensions to standard General Relativity, gravity has risen an interest given the possibility of coupling between geometry and matter. We examine the simplest model with nonminimal coupling in the context of cosmology. We pay special attention to the question of how far this model could reproduce the observational fact of our universe.
