We derive a ``generic'' inhomogeneous ``bridge'' solution for a cosmologicalmodel in the presence of a real self-interacting scalar field. This solutionconnects a Kasner-like regime to an inflationary stage of evolution andtherefore provides a dynamical mechanism for the quasi-isotropization of theuniverse. In the framework of a standard Arnowitt-Deser-Misner Hamiltonianformulation of the dynamics and by adopting Misner-Chitr\`e-like variables, weintegrate the Einstein-Hamilton-Jacobi equation corresponding to a ``generic''inhomogeneous cosmological model whose evolution is influenced by the couplingwith a bosonic field, expected to be responsible for a spontaneous symmetrybreaking configuration. The dependence of the detailed evolution of theuniverse on the initial conditions is then appropriately characterized.Comment: 17 pages, no figure, to appear on PR
