6‐regular 4‐critical graph

Journal of Graph Theory, 2002
AbstractP. Erdős conjectured in [2] that r‐regular 4‐critical graphs exist for every r ≥ 3 and noted that no such graphs are known for r ≥ 6. This article contains the first example of a 6‐regular 4‐critical graph. © 2002 Wiley Periodicals, Inc.

Total domination edge critical graphs

1998
A subset \(D\) of the vertex set \(V(G)\) of a graph \(G\) is called total dominating in \(G\), if for each \(x\in V(G)\) there exists a vertex \(y\in D\) adjacent to \(x\). The minimum number of vertices of a total dominating set in \(G\) is the total domination number \(\gamma_t(G)\) of \(G\).
