Bianchi type I expanding universe in Weyl-invariant gravity with a quartic interaction term
Abstract We will focus on the effect of a Weyl-invariant model with a quadratic interaction term and a free scalar field $$\psi $$ ψ . A set of analytic solutions will be obtained for this model. This model provides a dynamical alternative to the standard $$\Lambda $$ Λ CDM model. In particular, we...
