Anisotropic nature of space-time in $f(Q)$ gravity
Abstract
In this paper, we consider the Bianchi type-I space-time with perfect fluid as matter content of the Universe in the framework of gravity (where is the non-metricity scalar) recently proposed by Jim\'{e}nez et al. (Phys. Rev. D 98.4 (2018): 044048). We find exact solutions of the field equations using the anisotropic property of space-time for volumetric hybrid expansion. The cosmological parameters for the linear form of non-metricity scalar i.e. (where and are free model parameters) are discussed and compared with recent Hubble measurements. Also, we have obtained the best fitting values of the model parameters and by constraining our model with updated Hubble datasets consisting of 57 data points ( (DA) and (BAO+other)) along with also examined the stability of the model and test its validity by energy conditions.
