Key findings on coupling matter and geometry in cosmology

This paper develops cosmological solutions in a theory coupling matter and geometry. It applies a technique called gravitational decoupling to extend an isotropic matter distribution into an anisotropic one. This allows study of the universe's evolution, analyzing effects of the coupling and anisotropy. The radiation-dominated era is shown to be stable with this coupling.
