Abstract : An abstract theory of scattering is developed for dissipative hyperbolic systems; a typical example is the wave equation (u sub tt) = delta in an exterior domain with lossy boundary conditions: (u sub n) + alpha (u sub t) = O, alpha > or  O. In this theory as in an earlier one developed by the authors for conservative systems, a central role is played by two distinguished subspaces of data common to both the perturbed and the unperturbed problems; these are the incoming and outgoing subspaces. The scattering matrix is obtained and characterized in terms of generalized incoming and outgoing eigenfunctions. (Author)
