WebDomination Parameters of a Graph and its Complement 205 total domination in graphs has been surveyed and detailed in the recent book [10]. A survey of total domination in graphs can also be found in [9]. Another way of looking at total domination is that a dominating set S is a TD-set if the induced subgraph G[S] has no isolated vertices. WebSquaregraphs were originally defined as finite plane graphs in which all inner faces are quadrilaterals (i.e., 4-cycles) and all inner vertices (i.e., the vertices not incident with the outer face ...

Web(c)Find a simple graph with 5 vertices that is isomorphic to its own complement. (Start with: how many edges must it have?) Solution: Since there are 10 possible edges, Gmust have 5 edges. One example that will work is C 5: G= ˘=G = Exercise 31. (a)Draw the isomorphism classes of connected graphs on 4 vertices, and give the vertex and edge The fact that the complement of a perfect graph is also perfect is the perfect graph theorem of László Lovász.
