Some generalized soliton solutions of the cosmological Einstein–Rosen type defined in the space‐time region t2≥z2 in terms of canonical coordinates are considered. Vacuum solutions are studied and interpreted as cosmological models. Fluid solutions are also considered and are seen to represent inhomogeneous cosmological models that become homogeneous at t→∞. A subset of them evolve toward isotropic Friedmann–Robertson–Walker metrics.
