Abstract

A four dimensional spherically symmetric cosmological model with cosmic string and bulk viscosity in Lyra Geometry has been considered. The solution for cloud string model𝜌 + 𝜆𝑠 = 0yields that, the spatial volume decreases with increase of time, i.e. the universe is contracting with a constant deceleration and shows anisotropy throughout the evolution. Themodel is non-rotating, not a recurrent space and also not a space of constant curvature in generalized curved space.

Keywords
