Interacting dark energy in curved FLRW spacetime from Weyl Integrable Spacetime

Understand

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-Lemna\^{i}tre-Robertson-Walker geometry for the universe.
• We show that widely-known phenomenological interacting cosmological scenarios can naturally appear in this context.
• We then performed the dynamical system analysis of the underlying cosmological scenario and explored many possibilities extracted from this gravitational theory.
