Roman domination on graphs [PDF]

, 2010
A Roman dominating function of a graph G is a function f : V (G) → {0, 1, 2} such that whenever f(v) = 0 there xists a vertex u adjacent to v such that f(u) = 2. The weight of f is w(f) = Pv∈V (G) f(v).

Strongly chordal graphs as intersection graphs of trees (Farber's proof revisited)

CoRR
In his Ph.D. thesis, Farber proved that every strongly chordal graph can be represented as intersection graph of subtrees of a weighted tree, and these subtrees are ``compatible''. Moreover, this is an equivalent characterization of strongly chordal graphs. To my knowledge, Farber never published his results in a conference or a journal, and the thesis

Graph Isomorphism Completeness for Chordal Bipartite Graphs and Strongly Chordal Graphs

Graph Isomorphism Completeness for Chordal Bipartite Graphs and Strongly Chordal Graphs
This paper deal with the graph isomorphism (GI) problem for two graph classes: chordal bipartite graphs and strongly chrdal graphs. It is known that GI problem is GI complete for some special graph classes including regular graphs, bipartite graphs, chordal graphs, comparability graphs, split graphs, and k-trees for unbounded k.
