ABSTRACT: In this paper homogeneous Bianchi type -I space-time
with variable G and L containing matter in the form of a perfect fluid assuming the cosmological term
proportional to H2 (where H is Hubble Parameter). Initially the model has a
point type singularity, gravitational constant G (t) is decreasing and
cosmological constant L is
infinite at this time. When time increases,L decrease. The model does not
approach isotropy, if it is small. The model is quasi-isotropic for large value of it.
