This paper addresses the problem of de ning views that span several objectbases. Views are expressed in terms of an object algebra. We are interested in the degrees of coupling an...
Algebraic multigrid methods offer the hope that multigrid convergence can be achieved (for at least some important applications) without a great deal of effort from engineers an...
