“…The proposed domain decomposition multigrid algorithm belongs to the class of non-iterative domain decomposition methods, which have been previously studied by several authors in the context of parabolic problems (see, e.g., [27,31,38,44,45] in the overlapping case, and [10,11,14,21,22,40,[49][50][51] in the non-overlapping case). To be precise, we formulate a non-overlapping domain decomposition scheme that extends the ideas discussed in [46] for linear diffusion equations on rectangular meshes to the case of nonlinear reaction-diffusion problems on triangular grids.…”
