Transversal Structures in Graph Systems: A Survey

Wanting Sun, Guanghui Wang, Lan Wei

Given a system $G = {G_{1}, G_{2}, \dots, G_{m}}$ of graphs/digraphs/hypergraphs on the common vertex set $V$ of size $n$ , an $m$ -edge graph/digraph/hypergraph $H$ on $V$ is tran…

Transversal Hamilton paths and cycles

Yangyang Cheng, Wanting Sun, Guanghui Wang +1

Given a collection $G = {G_{1}, G_{2}, \dots, G_{m}}$ of graphs on the common vertex set $V$ of size $n$ , an $m$ -edge graph $H$ on the same vertex set $V$ is transversal in $\mat…
