On the extremal number of incidence graphs

Jisun Baek, David Conlon, Joonkyung Lee

Given a graph $H$ and a natural number $n$ , the extremal number $ex (n, H)$ is the largest number of edges in an $n$ -vertex graph containing no copy of $H$ . In this paper,…

On norming systems of linear equations

Seokjoon Cho, David Conlon, Joonkyung Lee +2

A system of linear equations $L$ is said to be norming if a natural functional $t_{L} (\cdot)$ giving a weighted count for the set of solutions to the system can be used to define a n…

Around the positive graph conjecture

David Conlon, Joonkyung Lee, Leo Versteegen

A graph $H$ is said to be positive if the homomorphism density $t_{H} (G)$ is non-negative for all weighted graphs $G$ . The positive graph conjecture proposes a characterisation of su…
