Energy exchange for homogeneous and isotropic universes with a scalar field coupled to matter
Roberto Giambo', John Miritzis
We study the late time evolution of flat and negatively curved Friedmann-Robertson-Walker (FRW) models with a perfect fluid matter source and a scalar field arising in the conforma…
