Abstract

In this paper, we survey some new results in four areas of domination in graphs, namely:

(1) the toughness and matching structure of graphs having domination number 3 and which are "critical" in the sense that if one adds any missing edge, the domination number falls to 2;

(2) the matching structure of graphs having domination number 3 and which are "critical" in the sense that if one deletes any vertex, the domination number falls to 2;

(3) upper bounds on the domination number of cubic graphs; and

(4) upper bounds on the domination number of graphs embedded in surfaces.

Keywords: domination, matching, toughness, cubic graph, triangulation, genus.
