Assume G has 11 vertices. G and its complement G* together will have C(11,2) = 55 edges. Since m =< 3n -6 in simple planar graphs, neither G nor G* can have more than 3(11 ... The fact that the complement of a perfect graph is also perfect is the perfect graph theorem of László Lovász. Cographs are defined as the graphs that can be built up from single vertices by disjoint union and complementation operations. They form a self-complementary family of graphs: the complement of any … See more In the mathematical field of graph theory, the complement or inverse of a graph G is a graph H on the same vertices such that two distinct vertices of H are adjacent if and only if they are not adjacent in G. That is, to generate the … See more Several graph-theoretic concepts are related to each other via complementation: • The complement of an edgeless graph is a complete graph and vice versa. • Any induced subgraph of the complement graph of a graph G is the complement of the corresponding … See more In the analysis of algorithms on graphs, the distinction between a graph and its complement is an important one, because a See more Let G = (V, E) be a simple graph and let K consist of all 2-element subsets of V. Then H = (V, K \ E) is the complement of G, where K \ E is the See more A self-complementary graph is a graph that is isomorphic to its own complement. Examples include the four-vertex path graph and … See more
