Thermodynamic constraints and future singularities in Unimodular Gravity driven by phantom and non-phantom fluids

Norman Cruz, Samuel Lepe, Guillermo Palma +1

This work investigates future cosmological singularities in a flat FLRW universe filled with a single barotropic fluid, ($p=({\hat{I}}^3-1)\ddot{I}$), within the framework of unimodular gravit…
