Abstract

The present study deals with Lyra's geometry in plane symmetric metric discussed in the presence of bulk viscous fluid and one dimensional strings are assumed to be loaded with particles and the particle energy density. The variation of Hubble's parameter gives a constant value of decelerating parameter. The exact solution has been found for the plane symmetric model in Lyra's geometry in the framework of bulk viscosity and string cosmology. Also, the bulk viscous pressure is assumed to be proportional to the energy density. The physical and geometrical properties of the model are also discussed.
