Structural Origin of Cosmological Density Ratios: $\Omega_m^2 = 3\Omega_\Lambda \Omega_b$

This work investigates a simple algebraic relation among cosmological density parameters $$\Omega_m^2 \approx 3\,\Omega_\Lambda\,\Omega_b$$ suggested by representative late-time cosmological parameter estimates reported by Planck and DESI analyses. The framework uses the fixed st...
