| Abstract: | This paper states new developments of extrapolation methods and combination techniques for solutions of multi-dimensional problems. It contains splitting extrapolation and its applications to the partial differential equation, the multi-dimensional integral equation and the numerical multiple integration, the sparse grid method and combination method for solving boundary integral equations. The numerical examples given in this paper show that these methods are very efficient for solutions of multi-dimensional problems. |
