Abstract

In this paper investigation of conharmonically flat FRW spacetime is considered in presence of perfect fluid as a matter source To get the deterministic model we have employed the condition between vacuum density Λ and the Hubble parameter H as Λ=3βH 2 where β is a constant Astrophys Space Sci 31483 2008 Physical features of the model are discussed in detail An estimate of the statefinder and snap parameters is also carried out for the model The observed values of these parameters agree ΛCDM model We see that the model is in agreement with recent observations
