Scalar field in Bianchi type-I cosmology with Lyra's geometry

In this study, we examine the role of a scalar field in the evolution of the Universe within the framework of a Bianchi type-I cosmological model with Lyra’s geometry. Previous research has explored the nonlinear spinor field in various anisotropic and isotropic cosmological models. In our current study, we and dynamical restrictions for Lyra parameters and violation of stress-energy tensor conservation within Lyra geometry. We shown that in considering cases behavior of Lyra’s parameter corresponds to relative in?uence in early universe and absence of Lyra geometry in present universe.
