Geometric deformations of symmetric spacetimes with a string cloud
A single-function deformation of 3D eta-Einstein metrics produces 4D Einstein spacetimes sourced by a string cloud, covering FLRW, Kantowski-Sachs, LRS Bianchi, Taub-NUT-(A)dS, and Reissner-Nordstrom-(A)dS solutions with spherical, planar or hyperbolic symmetry.
