 note = {application/pdf, 紀要論文, Spaces are determined such that they satisfy Einstein's field equations for empty spaces with or without cosmological terms and that the equation of geodesic there is integrable by separation of variables. A new space with cosmological terms is obtained which may be represented as the intersection of two cylindrical surfaces in a six dimensional euclidian space.},
