A dual-head PINN couples H(z) and fσ8(z) through the GR growth ODE; with SH0ES or H0dN priors, fσ8 is systematically suppressed relative to ΛCDM while Om(z) is non-flat.

Joint reconstruction of $H(z)$ and $f\sigma_8(z)$ with physics informed neural networks
A dual-head PINN couples H(z) and fσ8(z) through the GR growth ODE; with SH0ES or H0dN priors, fσ8 is systematically suppressed relative to ΛCDM while Om(z) is non-flat.
