iDCDM adds two parameters to LambdaCDM so that dark matter decay produces late-time interacting radiation, yielding a distinctive low-redshift suppression of structure growth while leaving BBN and primary CMB unchanged.

A field-level CNN emulator converts MG-PICOLA runs into near N-body accuracy for f(R) gravity and neutrino cosmologies, achieving sub-percent errors on power spectra and bispectra while generalizing beyond its training set.
Joint lensing-kinematics analysis of nine CLASH clusters constrains chameleon gravity, yielding GR-consistent bounds for NFW and Hernquist profiles and |f_R| ≲ 2-5×10^{-5} for f(R) models.
A holographic f(Q) = ζ Q^n model yields slow-roll inflation consistent with Planck 2018 and late-time expansion compatible with CC+BAO data via CPL parametrization, with mild high-z deviations from ΛCDM.
The work claims to build generalized manifold-metric pairs, prove metrizability via the Urysohn theorem, introduce higher-rank tensor metrics and complex/quaternionic structures, and apply them to cosmological expanding spacetimes within a unified information-theoretic framework.
