Workshop Summary:

Recently, the subject of approximate inverses (AI) has attracted new attention. Many new developments show the promise of this technique. The motivation for this renewed interest is largely from parallel processing. However, new progress in this subject has provided an extra boost. The new preconditioners are useful in some areas where ILU preconditioners failed. A new class of powerful smoothers using AI for multigrid has been developed. The understanding of this technique has reached a new level in the past 10 years. AI is successfully applied to some challenging industrial applications. In this workshop, we present some of the latest developments in these directions.
