Biholes in balanced bipartite graphs (2004.03245v2)
Published 7 Apr 2020 in math.CO
Abstract: A bihole in a bipartite graph $G$ with partite sets $A$ and $B$ is an independent set $I$ in $G$ with $|I\cap A|=|I\cap B|$. We prove lower bounds on the largest order of biholes in balanced bipartite graphs subject to conditions involving the vertex degrees and the average degree.
