The inducibility of 6-vertex graphs

Levente Bodnár, Jun Gao, Jared León +3

The inducibility constant of a graph is the asymptotically maximum induced density of in a growing sequence of graphs. This paper systematically investigates the c…

Strong non-principality of positive codegree Turán density

Levente Bodnár, Jun Gao, Oleg Pikhurko +2

The \emph{minimum positive codegree} of a -graph is the minimum, over all -sets that lie in at least one edge, of the number of edges containing that…

A note on the Ratio and Inertia Bounds for the -Independence Number

Jun Gao, Jie Ma, Oleg Pikhurko

The -th power of a graph is the graph on the same vertex set where the edge set consists of those pairs of distinct vertices of that are at distance at most fr…
