Exact Homomorphism Thresholds Beyond Cliques

Xinqi Huang, Mingyuan Rong, Chong Shangguan

The chromatic threshold, originating in a question of Erdős and Simonovits, asks when a linear minimum-degree condition forces bounded chromatic number in H-free graphs. Motivated…

On the spectrum and structure of blowup thresholds

Xinqi Huang, Hong Liu, Mingyuan Rong

The chromatic threshold of Erdős and Simonovits asks when a minimum-degree condition forces every \(H\)-free graph to have bounded chromatic number. Thomassen's homomorphism thresh…

Optimal stability results on color-biased Hamilton cycles

Wenchong Chen, Mingyuan Rong, Zixiang Xu

We investigate Hamilton cycles in edge-colored graphs with \( r \) colors, focusing on the notion of color-bias (discrepancy), the maximum deviation from uniform color frequencies…

Largest dyadic dual VC-dimension of non-piercing families

Xinqi Huang, Yuzhen Qi, Mingyuan Rong +1

The dyadic dual VC-dimension of a set system \( \mathcal{F} \) is the largest integer \( \ell \) such that there exist \( \ell \) sets \( F_1, F_{2}, \dots, F_\ell \in \mathcal{F}…

Interpolating chromatic and homomorphism thresholds

Xinqi Huang, Hong Liu, Mingyuan Rong +1

The problem of chromatic thresholds seeks for minimum degree conditions that ensure -free graphs to have a bounded chromatic number, or equivalently a bounded size homomorphic i…

Sublinear hitting sets for some geometric graphs

Xinbu Cheng, Xinqi Huang, Mingyuan Rong +1

For an -vertex graph , let denote the smallest size of a subset of such that it intersects every maximum independent set of . A conjecture posed by Bollobás,…
