Much of our current knowledge on graph isomorphism testing is summarized in Babai, Luks [BL83]. The general concept of reconstruction (invertibility of various constructions) is illustrated in Chapter 15 of Lov´asz [Lov79a]. Recent surveys on the Kelly-Ulam graph reconstruction conjecture include Bondy [Bon91 ...

WebA graph isomorphism is a bijection between the vertex sets of two graphs such that two vertices in one graph are adjacent if and only if the corresponding two vertices in the other graph are adjacent. Isomorphic graphs are viewed as being the same graph. Within a graph, two vertices that are joined by an edge are said to be adjacent, or neighbours. WebAn automorphism of a graph is a graph isomorphism with itself, i.e., a mapping from the vertices of the given graph back to vertices of such that the resulting graph is isomorphic with .
