Effective CDM model emerging from under a special EOS limit in symmetric cosmology with Bayesian and ANN observational constraints
Anil Kumar Yadav, S. H. Shekh, N. Myrzakulov +3
In this work, we investigate the cosmological consequences of an effective CDM model emerging from the more general gravity theory under the special equation-of-state c…
