This paper deals with the cosmological models for the static spherically symmetric spacetime for perfect fluid with anisotropic stress energy tensor in general relativity by introducing the generating functions g r and w r and also discussing their physical and geometric properties.
In this paper, we have obtained plane symmetric cosmological models of thick domain walls with viscous field coupled with electromagnetic field in the framework of Lyra geometry, by using equation of state. Physical and geometrical implications of the models are also discussed in the presence of magnetic field.
We have investigated Bianchi type-IX dust filled universe for ideal fluid distribution in creation field in which creation field is a function of time t only. To get deterministic cosmological model, we have assumed a supplementary condition a = b n , where a and b are metric potential and n is constant. Also, we have study the physical and geometrical parameters of the said cosmological model.
In this paper, we have shown that generalized plane wave metric be the solution of Einstein-Maxwell equations in the presence of null fluid and null currents in higher dimensional space-time V 5 for Z = t z -type plane wave and also discussed some particular cases.
