摘要
In this paper, we have investigated that tilted Bianchi Type I cosmological models for stiff perfect fluid under a supplementary condition A=B-n between metric potentials, is not possible. The tilted solution is also not possible when we assume A=t(l), B=t(m), C=t(n); l, m and n are constants for epsilon=p. Thus to preserve tilted nature of model, we assume p=gammaepsilon, 0less than or equal togammaless than or equal to1 (barotropic equation of state) for the case A=t(l), B=t(m) and C=t(n). The physical and geometrical aspects of the models are also discussed.
