Strong binding numbers and factors

Guantao Chen, Mikhail Lavrov, Yuying Ma +2

Let $G$ be a simple graph. The $k$ -th neighborhood of a vertex subset $S \subseteq V (G)$ , denoted $I^^{k} (S)$ , is the set of vertices that are adjacent to at least $k$ vertices in $S…

Bipartite graphs with the double Hall property

Guantao Chen, Mikhail Lavrov, Yuying Ma +2

The super-neighborhood of a vertex set $A$ in a graph $G$ , denoted by $I^^{2} (A)$ , is the set of vertices adjacent to at least two vertices in $A$ . We say that a bipartite graph $G=(…
