Abstract
A spectral domain decomposition scheme is introduced for the numerical solution of second- and fourth-order elliptic problems. The technique is applicable to certain domain decompositions of rectangular or rect angularly decomposable domains. It is shown that it yields approximati ons which are pointwise C-0 continuous across the subdomain interfaces for second order problems and pointwise C-1 continuous across the sub domain interfaces for fourth-order problems.
