On zero-sum free sequences contained in random subsets of finite cyclic groups

Sang June Lee, Jun Seok Oh

Let $C_{n}$ be a cyclic group of order $n$ . A sequence $S$ of length $ℓ$ over $C_{n}$ is a sequence $S = a_{1} \cdot a_{2} \cdot \dots \cdot a_{ℓ}$ of…

AK-type stability theorems on cross t-intersecting families

Sang June Lee, Mark Siggers, Norihide Tokushige

Two families, $A$ and $B$ , of subsets of $[n]$ are cross $t$ -intersecting if for every $A \in A$ and $B \in B$ , $A$ and $B$ intersect in…

The independence number of non-uniform uncrowded hypergraphs and an anti-Ramsey type result

Sang June Lee, Hanno Lefmann

We prove the following: Fix an integer $k \geq 2$ , and let $T$ be a real number with $T \geq 1.5$ . Let $\cH=(V,\cE_2\cup \cE_3\cup\dots\cup\cE_k)$ be a non-uniform hypergraph with th…

On the total variation distance between the binomial random graph and the random intersection graph

Jeong Han Kim, Sang June Lee, Joohan Na

When each vertex is assigned a set, the intersection graph generated by the sets is the graph in which two distinct vertices are joined by an edge if and only if their assigned set…

On Sidon sets in a random set of vectors

Sang June Lee

For positive integers $d$ and $n$ , let $[n]^{d}$ be the set of all vectors $(a_{1}, a_{2}, \dots, a_{d})$ , where $a_{i}$ is an integer with $0 \leq a_{i} \leq n - 1$ . A subset $S$ of $[n]^{d}$ is call…

On constant-multiple-free sets contained in a random set of integers

Sang June Lee

For a rational number $r > 1$ , a set $A$ of positive integers is called an $r$ -multiple-free set if $A$ does not contain any solution of the equation $r x = y$ . The extremal problem o…
