Abstract
In the present article, we show that a simple modification to the Einstein-Hilbert action can explain the possibility of mutual interaction between the cosmic fluids. That is achieved considering the Weyl Integrable Spacetime in the background of a nonflat Friedmann-Lemaître-Robertson-Walker geometry for the universe. We perform the dynamical system analysis of the underlying cosmological scenario and explore many possibilities extracted from this gravitational theory. Finally, we investigate if the specific model solves the flatness problem.
