Bulk Viscous String Cosmological Models in Lyra Geometry

V. U. M. Rao, U. Y. Divya Prasanthi


In this paper we have obtained and presented a new class of spatially homogeneous Kantowski – Sachs cosmological models in the presence of bulk viscous cosmic strings in the frame work of a theory of gravitation proposed by Sen (1957) based on Lyra (1951) geometry. To obtain a solution, it is assumed that expansion scalar is proportional to shear scalar i.e. θ ∝s2, which leads to a relation between metric potentials. Some physical and geometrical aspects of the results are also discussed.
