摘要

In this paper, we evaluate the general solutions for plane-symmetric thick domain walls in Lyra geometry in presence of bulk viscous fluid.Expressions for the energy density and pressure of domain walls are derived in both cases of uniform and time varying displacement field β.Some physical consequences of the models axe also given.Finally, the geodesic equations and acceleration of the test particle are discussed.
