Abstract

In this paper, we study the domain wall with time dependent displacement vectors based on Lyra geometry in normal gauge i.e. displacement vector fi=[β(t),0,0,0]f^*_i = [ \beta (t), 0,0,0]. The field theoretic energy momentum tensor is considered with zero pressure perpendicular to the wall. We find an exact solutions of Einstein equation for a scalar field ϕ\phi with a potential V(ϕ)V(\phi) describing the gravitational field of a plane symmetric domain wall. We have seen that the hyper surfaces parallel to the wall (z=constant z = constant ) are three dimensional de-sitter spaces. It is also shown that the gravitational field experienced by test particle is attractive.
