Cyclic Sources of Strong Domination in Graph Norms

Shuyan Chen

Conlon and Lee asked for strongly dominating graphs beyond norming graphs and even paths. We construct a two-parameter family of pairwise non-isomorphic $2$ -connected strongly domi…

Odd-Cycle Span Defect: A Polynomial Lower Bound and a Square-Root Upper Bound

Shuyan Chen

For a graph $G$ , let $I ¨ (G) = max {I ¨ (G [V (C)]) : C$ is an odd cycle of $G}$ , with $I ¨ (G) = 0$ when $G$ is bipartite. For positive integers $N$ , set $F(N)=\max\{Ï(G)-Ï(G):|V(G)|\le N\…
