摘要：
Evolution of a homogeneous, isotropic Universe with flat geometry filled with a viscous fluid is investigated in presence of a variable cosmological Lambda. A non-singular solution leading to a variable deceleration parameter is obtained which reduces to the solution of Murphy in the 'no Lambda limit' and to the recent solution of Vishwakarma in the context of 'a Machian model of dark energy' in the 'no viscosity' limit.
