- Descripción
- A new class of exact expanding inhomogeneous solutions of the Einstein-Maxwell equations is derived. These solutions generalize the dust filled models found by Ruban and the Doroshkevich "magnetic" universes. In the most general case the cosmological constant is non-zero and the matter content is a mixture of two interacting perfect fluids plus a sourceless electromagnetic field. The influence of the field near the singularity and at the latter stages of the expansion is examined. A subclass of the models approaches homogeneity and isotropy for large cosmological times.
