SANCHEZ, Alberto; MACIAS, Alfredo  y  QUEVEDO, Hernando. A method for generating Gowdy cosmological models. Rev. mex. fis. [online]. 2007, vol.53, suppl.2, pp.110-114. ISSN 0035-001X.

Numerical methods have been extensively used to investigate Gowdy models, but only recently it has been argued that solutions-generating techniques can be applied in this case to generate new solutions. In this work, we concentrate on T³ Gowdy cosmological models and shall see that a complex coordinate transformation, together with a complex change of metric functions, allows us to apply, in a straightforward manner, the well-known solution-generating techniques that have been intensively used for stationary axisymmetric solutions.
