Some features of the Bianchi type-I universes in the presence of a fluid that wields an anisotropic equation of state (EoS) parameter are discussed in the context of general relativity. The models tha...
Tilted Bianchi Type I dust fluid magnetized cosmological model in general relativity
Bianchi type I dust fluid tilted models
