On hamiltonian line-graphs [PDF]
Introduction. The line-graph L(G) of a nonempty graph G is the graph whose point set can be put in one-to-one correspondence with the line set of G in such a way that two points of L(G) are adjacent if and only if the corresponding lines of G are adjacent.

Graph Homomorphism Revisited for Graph Matching [PDF]
In a variety of emerging applications one needs to decide whether a graph G matches another Gp, i.e., whether G has a topological structure similar to that of Gp. The traditional notions of graph homomorphism and isomorphism often fall short of capturing

Reactivity effects of concurrent verbalisation during a graph comprehension task [PDF]
We report an experiment investigating how concurrent verbalisation during a task can affect performance (a so-called “reactivity” effect). Participants studied three-variable line graphs while (a) concurrently thinking aloud or (b) silently studied the ...

Abstract We characterize Borel line graphs in terms of 10 forbidden induced subgraphs, namely the nine finite graphs from the classical result of Beineke together with a 10th infinite graph associated with the equivalence relation $\mathbb {E}_0$ on the Cantor space.

A graph’s b-coloring admits proper coloring and has the extra characteristic of having a dominating node in each color-class in the graph. [Formula: see text] the b-chromatic number, is the largest integer k for which G can be colored with k colors using

Coalition structures induced by the strength of a graph [PDF]
We study cooperative games associated with a communication structure which takes into account a level of communication between players. Let us consider an undirected communication graph : each node represents a player and there is an edge between two ...

Line and Subdivision Graphs Determined by
Let T 4 = { ± 1 , ± i } be the subgroup of fourth roots of unity inside T , the multiplicative group of complex units. For a T 4 -gain graph Φ = ( Γ , T 4 , φ ) , we introduce gain functions on ...
