abstract

We explore the introduction of the cosmological constant via equivalent transformations in cosmology. We consider the Wheeler-DeWitt equation for the CDM universe and we construct the Hamilton-Jacobi action for the $\Lambda$CDM model. We discuss how this approach allows us to relate different physical systems, providing insights into the role of the cosmological constant in cosmology.

  1. Cosmological Solutions in Scalar-Tensor theory via the Eisenhart-Duval lift

    gr-qc 2025-01 reject novelty 5.0 of 10

    By adding an extra dimension through the Eisenhart-Duval lift and requiring conformal flatness, the author finds scalar-tensor cosmologies whose field equations reduce to linear equations with power-law solutions.
