Kaluza-Klein cosmological model in f ( R , T ) $f(R,T)$ gravity with domain walls

Abstract

We have investigated the physical behavior of the five dimensional Kaluza-Klein cosmological model in the frame work of $f(R,T)$ theory of gravity in presence of domain walls. Here, $R$ is the Ricci scalar and $T$ is the trace energy tensor. To determine the solution of field equation, we have considered the special law of variation parameter proposed by Berman (Nuovo Cimento 74B:182, 1983) that yields a constant deceleration parameter. Some physical properties of the model are discussed.
