Abstract : One paper produced in this effort dealt with the importance of intermediate boundary conditions for approximate factorization schemes. A second paper derived stability results for spectral methods applied to initial-boundary value problems for hyperbolic systems. The paper demonstrates that one can bound certain weighted L2 spatial norms of the solution in terms of norms of the boundary data. A third paper deals with domain decomposition methods in the content of spectral techniques. Stability and convergence results are obtained for one and two dimensional cases.
