PINN-based joint reconstruction of H(z) and fσ8(z) coupled through the GR growth equation recovers the input H0 prior exactly, yields fσ8(z) below ΛCDM at all redshifts, and shows Om(z) departure from flat ΛCDM at low z.
The f(Q, L_m) gravity model fits observational data from BBN to late-time acceleration, acting as a viable quintessence-like alternative to the standard LambdaCDM model.
Re-expressing the Hubble tension via posterior-implied E(z) histories yields moderate mismatches (S_hist of 1.65 and 2.55) that correspond to only 1.1-2.1 sigma equivalents, below the usual 4.9 sigma scalar-H0 discrepancy.
The authors constrain power-law f(T) teleparallel gravity models via logarithmic and log-periodic deceleration parameter ansatzes fitted to cosmic chronometer and Pantheon datasets, finding departure from ΛCDM.
In f(T) gravity with Gong-Zhang EoS parametrization, the fitted model shows transient acceleration followed by future deceleration and satisfies thermodynamic consistency.

Beyond the equation of state: a second-order diagnostic for dynamical dark energy
Introduces curvature diagnostic C = ρ_DE''/ρ_DE for two-fluid interacting dark energy models that isolates ω_DE' independently of interaction strength α and recovers it in CPL parametrization consistent with DESI data.

Joint reconstruction of $H(z)$ and $f\sigma_8(z)$ with physics informed neural networks
PINN-based joint reconstruction of H(z) and fσ8(z) coupled through the GR growth equation recovers the input H0 prior exactly, yields fσ8(z) below ΛCDM at all redshifts, and shows Om(z) departure from flat ΛCDM at low z.

From Scalar $H_0$ to $E(z)$: A Reformulation of the Hubble Tension
Re-expressing the Hubble tension via posterior-implied E(z) histories yields moderate mismatches (S_hist of 1.65 and 2.55) that correspond to only 1.1-2.1 sigma equivalents, below the usual 4.9 sigma scalar-H0 discrepancy.
