Abstract. We have investigated non-diagonal Bianchi type IV space-time filled with perfect fluid in the framework of gravity, where is the Ricci scalar and is the trace of the energy-momentum tensor. We have considered two cases of gravity: and . In both the cases, it is found that the perfect fluid does not survive and the space-time turns out to be flat in theory of gravity.
