Mapping solutions in nonmetricity gravity: Investigating cosmological dynamics in conformal equivalent theories
Abstract
We investigate the impact of conformal transformations on the physical properties of solution trajectories in nonmetricity gravity. Specifically, we explore the phase space and reconstruct the cosmological history of a spatially flat Friedmann-Lemaitre-Robertson-Walker universe within scalar-nonmetricity theory in both the Jordan and Einstein frames. A detailed analysis is conducted for three connections defined in the coincident and non -coincident gauges. Our findings reveal the existence of a unique one-to-one correspondence for equilibrium points in the two frames. Furthermore, we demonstrate that solutions describing accelerated universes remain invariant under the transformation that relates these conformally equivalent theories.
