Minisuperspace description for inhomogeneous cosmological models and the role of the Lie symmetries
We explore the application of Lie symmetries to simplify the gravitational field equations of inhomogeneous cosmology.By employing these symmetries, we demonstrate the construction of a point-like Lagrangian and establish the existence of a minisuperspace description.Finally we show how the Lie symmetries can be applied to construct new solutions for the Wheeler-DeWitt equation.
