Abstract:Bianchi type I string dust cosmological models in the presence and absence of magnetic field in the frame work of Lyra geometry are investigated. To get the deterministic model of the universe, we assume that the eigenvalue (σ11 ) of shear tensor (σi j ) is proportional to expansion (θ ). This leads to A =(BC)n, where A, B, C are metric potentials and n is a constant. To discuss the results in terms of cosmic time t, we have considered n = 1. The physical and geometrical aspects of the models and singularities in the models are also discussed.
Keywords:Bianchi I  string dust  magnetized  cosmological  Lyra geometry
