This novel technique is applied to generate, as examples, new spatially homogeneous and isotropic cosmologies, a 3-parameter family of spherical time-dependent spacetimes conformal to a Campanelli-Lousto geometry, and a family of cylindrically symmetric geometries.en10.1103/PhysRevD.97.064004info:eu-repo/semantics/openAccessExact Cosmological SolutionsBlack-HolesMachs PrincipleConstantEinsteinDualityArticle976N/AWOS:001250440000314
