摘要
We have investigated the cosmological implications of the bulk viscous cosmological model with variable G and Lambda. These results are found to be compatible with the present observations. The classical cosmological tests for this model encompass the Freese et al. ones. The model has some spirits of the Standard Model. The inflationary solution which solves the Standard problems is obtained as a special solution. The influence of viscosity is shown to affect the past and the future of the Universe.
