%0 Journal Article %T Global foliations of matter spacetimes with Gowdy symmetry %A Hakan Andreasson %J Physics %D 1998 %I arXiv %R 10.1007/s002200050708 %X A global existence theorem, with respect to a geometrically defined time, is shown for Gowdy symmetric globally hyperbolic solutions of the Einstein-Vlasov system for arbitrary (in size) initial data. The spacetimes being studied contain both matter and gravitational waves. %U http://arxiv.org/abs/gr-qc/9812035v1
