Kantowski-Sachs cosmological models with perfect fluid and time varying G and
L are presented. Exact solutions of the field equations are obtained by
using the scalar of expansion proportional to the shear scalar
q µ s,
which leads to a relation between the metric potentials A=Bn, where n
is a constant. The corresponding physical interpretation of the cosmological
solutions are also discussed.
