Resonance Graphs and Perfect Matchings of Graphs on Surfaces

Niko Tratnik, Dong Ye

Let $G$ be a graph embedded in a surface and let $F$ be a set of even faces of $G$ (faces bounded by a cycle of even length). The resonance graph of $G$ with respect to $\…

Toughness and spanning trees in $K_{4}$ -minor-free graphs

M. N. Ellingham, Songling Shan, Dong Ye +1

For an integer $k$ , a $k$ -tree is a tree with maximum degree at most $k$ . More generally, if $f$ is an integer-valued function on vertices, an $f$ -tree is a tree in which each vert…
