摘要：
Thermodynamical behavior of inhomogeneous universe with varying I > in presence of electromagnetic field is obtained. F (12) is the non-vanishing component of electromagnetic field tensor. To get a deterministic solution, it is assumed that the free gravitational field is Petrov type-II non-degenerate. The value of cosmological constant is found to be small and positive supported by recent results from the supernovae observations recently obtained by High-Z Supernovae Ia Team and Supernovae Cosmological Project. A relation between cosmological constant and thermodynamical quantities is established. Some physical and geometric properties of the model are also discussed.
