Energy conditions in f ( R , L m ) gravity

Year: 2012

Type: article

Abstract: In order to constrain f ( R , L m ) gravity from theoretical aspects, its energy conditions are derived in this paper. These energy conditions given by us are quite general and can be degenerated to the well-known energy conditions in general relativity and f ( R ) theories of gravity with arbitrary coupling, non-minimal coupling and non-coupling between matter and geometry, respectively, as special cases. To exemplify how to use these energy conditions to restrict f ( R , L m ) gravity, we consider a special model in the FRW cosmology and give some corresponding results by using astronomical observations.
