On the automorphism group of a johnson graph
Web1 de jul. de 2024 · An asymmetric coloring of a graph is a coloring of its vertices that is not preserved by any non-identity automorphism of the graph. The motion of a graph is the minimal degree of its automorphism group, i.e., the minimum number of elements that are moved (not fixed) by any non-identity automorphism. We confirm Tom Tucker's “Infinite … WebUsing an analysis of the clique structure and only the most elementary group theory, we determine the automorphism group of the Johnson graph $J(n,i)$, for $n\neq2i$. …

Web1 de nov. de 2024 · As an application, we confirm Babai's conjecture on the minimal degree of the automorphism group of distance-regular graphs of bounded diameter. This … WebA continuous-time quantum walk on a graph G is given by the unitary matrix U ( t ) = exp ( − i t A ) , where A is the adjacency matrix of G . We say G has pretty good state transfer between vertices a and b if for any ϵ > 0 , there is a time t , where the ( a , b ) -entry of U ( t ) satisfies U ( t ) a , b ≥ 1 − ϵ . This notion was introduced by Godsil (2011).

Web4 de ago. de 2024 · Let G be a graph on n vertices. Here is a way to find aut ( G), here we assume G is not labeled (as in the picture you provide). Begin by labeling the vertices of G with elements from { 1, 2, 3, …, n }, let us call this labeling L. Among all possible labelings of G find those that result in the same graph as the one the one labeled at 1. WebFormally, 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 (σ(u), σ(v)) also …
WebAn automorphism of a graph is a graph isomorphism with itself, i.e., a mapping from the vertices of the given graph G back to vertices of G such that the resulting graph is isomorphic with G. The set of automorphisms …
