Abstract: | We consider an Einstein spaceV of the Petrov type II or III admitting a group of motionsG of high order. First we calculate the composition law and topological structure ofG. ThenV (or its submanifolds of transitivity) is represented as the homogeneous spaceG/H ofG,H being a subgroup ofG, and the actionG onV and the topology ofV are determined. The topologies of the spacesV are as follows: 4 (spaceT*2), 4 of 3 T1 (spaceT
2), 4 (spaceT*3), 3 (submanifolds of transitivity in spaceT
3).In two cases (spacesT
2 andT
3) we have obtained metrics free of singularities. |
