A Test of <i>f</i>(<i>Q</i>,<i>C</i>) Gravity Model with Application to the Photometric Maximum

We review the f( Q,C ) gravity with its three models for the equation of state (EoS). We introduce three new models for the EoS and we derive the parameters of these six models from the Pantheon+ catalog. The comparison of the results is done with the dynamical dark energy cosmology and the standard cosmology or ΛCDM. The results are applied to the photometric maximum in the number of galaxies as a function of the redshift.
