摘要
Cylindrically symmetric inhomogeneous cosmological model for bulk viscous fluid distribution with electromagnetic held is obtained. The source of the magnetic field is due to an electric current produced along the z-axis. F-12 is the non-vanishing component of electromagnetic field tensor. To get the deterministic solution, it has been assumed that the expansion 0 in the model is proportional to the shear a. The values of cosmological constant for these models are found to be small and positive at late time, which are consistent with the results from recent supernovae la observations. Physical and geometric aspects of the models are also discussed in presence and absence of magnetic field.
