WebIn the mathematical field of graph theory, an automorphism of a graph is a form of symmetry in which the graph is mapped onto itself while preserving the edge– vertex connectivity. Formally, an automorphism of a graph G = (V, E) is a permutation σ of the vertex set V, such that the pair of vertices (u, v) form an edge if and only if the pair ... WebSep 4, 2024 · Graph Hole. Chvátal defines the term hole to mean "a chordless cycle of length at least four." The restriction "of length at least four" allows use of the term "hole" regardless of if the definition of "chordless cycle" is taken to already exclude cycles of length 3 (e.g., West 2002, p. 225) or to include them (Cook 2012, p. 197; Wikipedia).

The chromatic polynomial of a graph G is the polynomial C G ( k) computed recursively using the theorem of Birkhoff and Lewis. The theorem of Birkhoff and Lewis states: c G ( k) = c G − e ( k) − c G / e ( k) where e is any edge from G, and. G − e is the graph obtained from G by removing edge e.
