The codegree Turán density of tight cycles

Jie Ma, Mingyuan Rong

The codegree Turán density $γ (F)$ of a $k$ -uniform hypergraph $F$ is the minimum real number $γ \geq 0$ such that every $k$ -uniform hypergraph on sufficiently many $n$ vertices, in w…

Recent advances in arrow relations and traces of sets

Mingze Li, Jie Ma, Mingyuan Rong

The arrow relation, a central concept in extremal set theory, captures quantitative relationships between families of sets and their traces. Formally, the arrow relation $(n, m) \r…

On codegree Turán density of the 3-uniform tight cycle $C_{11}$

Jie Ma

Piga, Sanhueza-Matamala, and Schacht recently established that the codegree Turán density of 3-uniform tight cycles $C_{ℓ}$ is $1/3$ for $ℓ \in {10, 13, 16}$ and for all $\ell…
