Some definitions of central structures,stance sum. The nature of the facility to be constructed (such as a pipeline) could necessitate selecting a structure (such as a path) rather than just a point at which to locate the facility. Similarly, the facility may be required to "service" structures or areas within the network, and not just p

Equalities involving certain graphical distributions,e another. The common neighbor distribution (nd) is (n.,n.,n.,...,n.), where n. is the number of pairs of vertices having i common neighbors. These and other sequences have been introduced recently as tools in distinguishing pairs of nonisomorphic graphs (dd(G) works best for graphs of large diamete

A collection of sets related to the tutte polynomial of a matroid,of "internally passive" elements, and for each forest, or independent set, F, there is a unique basis B such that ψ(B) ⊆ F ⊆ B. In the context of matroids generally, we examine the structure of the collection of sets {ψ(B) : B is a basis}, particularly looking at the sequence of numbers of these set

https://doi.org/10.1007/3-540-29490-2 Woodrow : if the arcs of a tournament are two-colored, then there exists some vertex which is reachable from every other vertex via a monochromatic path. Next, as illustrative of the proof of a more technical result, it is shown that with one exception every 3-connected tournament contains two

Giorgio Pietramaggiori,Saja Schereres. Variants of the puzzle include a 4 × 4 × 4 cube and a 3 × 4 × 5 brick. In this paper, we show how to construct all k × . × m bricks with small sets of different pieces. A defective cube is a cube with one of its unit cubes missing. We show that every 2. × 2. × 2. defective cube can be constructe

G and is studied with the appropriate probabilistic considerations..We derive some general properties of RG(p). In particular, we obtain the
