Cosmological Models with a Varying -Term in Lyra's Geometry
V. K. Shchigolev
Cosmological models in Lyra's geometry are constructed and investigated with the assumption of a minimal interaction of matter with the displacement vector field and the dynamical…
Leaky-box approximation to the fractional diffusion model of cosmic rays
V. V. Uchaikin, R. T. Sibatov, V. V. Saenko
Two models of anomalous diffusion of cosmic ray in the leaky-box approximation are compared: one of them is based on the decoupled time-space Lévy flights and the other on fraction…
Cosmological Model of Interacting Tachyon Field
V. K. Shchigolev, M. P. Rotova
In this paper we investigate a tachyon field model in cosmology, provided its interaction with the quintessence or phantom fields.The model takes into account this interaction beyo…
Scalar Field Cosmology in Lyra's Geometry
V. K. Shchigolev, E. A. Semenova
The new classes of homogeneous cosmological models for the scalar fields are build in the context of Lyra's geometry. The different types of exact solution for the model are obtain…
