Irreducibility and Primitivity of Perron Complements: Application of the Compressed Directed Graph,The . is a smaller matrix derived in a natural way from a square nonnegative matrix. By compressing the directed graph of a nonnegative matrix in a certain way, we analyze fully the connected components, irreducibility and primitivity of its Perron complement with respect to a given subset of indices.

An Introduction to Chordal Graphs and Clique Trees, associated with advanced computer architectures. This paper is a unified and elementary introduction to the standard characterizations of chordal graphs and clique trees. The pace is leisurely, as detailed proofs of all results are included. We also briefly discuss applications of chordal graphs an

Cutting down on Fill Using Nested Dissection: Provably Good Elimination Orderings,s aim to find elimination orderings with either low fill, low operation count, or low elimination height. Though many heuristics seem to perform well in practice, there has been a marked absence of much theoretical analysis to back these heuristics. Indeed, few heuristics are known to provide any gu

Automatic Mesh Partitioning,s. This approach makes use of the underlying geometric structure of a given mesh and finds a provably good partition in random .(.) time. It applies to meshes in both two and three dimensions. The new method has applications in efficient sequential and parallel algorithms for large-scale problems in
