Pradhan, AnirudhLotemshi, I.2012-03-122012-03-122011-07-06http://hdl.handle.net/11007/1209We utilise a form for the Hubble parameter to generate a number of solutions to the Einstein field equations with variable cosmological constant and variable gravitational constant in the presence of a bulk viscous fluid. The Hubble law utilised yields a constant value for the deceleration parameter. A new class of solutions is presented in the Robertson-Walker spacetimes. The coefficient of bulk vis- cosity is assumed to be a power function of the mass density. For a class of solutions, the deceleration parameter is negative which is consistent with the supernovae Ia observations.enBulk viscous solutionsParameter-revisitedArticle
