Generating Gowdy cosmological models
Using the analogy with stationary axisymmetric solutions, we present a method
to generate new analytic cosmological solutions of Einstein's equation
belonging to the class of Gowdy cosmological models. We show that the
solutions can be generated from their data at the initial singularity and
present the formal general solution for arbitrary initial data. We exemplify
the method by constructing the Kantowski-Sachs cosmological model and a
generalization of it that corresponds to an unpolarized Gowdy model.Comment: Latex, 15 pages, no figure
