We introduce an extrapolation type discretization of differential operators on sparse grids based on the idea of the combination technique. Furthermore, we show the consistency of that discretization. Finally the equivalence of the new method with that of [griebel,schiekofer] is established.}, ps = {http://wissrech.ins.uni-bonn.de/research/pub/koster/kons.ps.gz} }
