摘要：

We report on new classes of exact diagonal inhomogeneous cosmological solutions to the scalar-tensor gravity equations. The solutions describe cylindrically symmetric universes filled with stiff perfect fluid. As a particular limiting case, new gravi-dilaton vacuum solutions are obtained. The spacetimes described by the solutions are singularity free and globally hyperbolic.
