FRW Domain Walls in Modified f(G) Theory of Gravitation

摘要

In this paper, we have studied Friedmann-Robertson-Walker space-time in the presence of domain walls in the framework of f(G) theory of gravitation. We propose the generalization of linearly varying deceleration parameter. It is observed that the universe is accelerating and expanding. The values of state finder parameters are close to ?CDM model. Some physical parameters of the obtained models are discussed in detail.
