【 摘 要 】

A conservative Galerkin domain decomposition method for time-dependent problems is given and analyzed. This method allows one to apply different domain decompositions at different time levels when necessary, in order to capture time-changing local phenomena, such as, propagating fronts or moving layers. Error estimates in the energy and L(2) norms are established. Numerical results are presented.
