Schreier Sets of Intervals, Super-Schreier Sets, and Catalan Numbers

Hung Viet Chu, Mariam Khaduri, Moiz M. Khokhar +1

A finite nonempty set $F \subset N$ is Schreier if $min F \geq ∣ F ∣$ . First, we prove a linear recurrence relation and compute initial counts for Schreier sets consisting of i…

Linear Recurrences of Generalized Schreier Sets Revisited

Hung Viet Chu, Zachary Louis Vasseur

For $p, q \in N$ , a finite nonempty set $F$ is said to be $(p, q)$ -Schreier (or maximal $(p, q)$ -Schreier, respectively) if $q min F \geq p ∣ F ∣$ (or $q min F = p ∣ F ∣$ , respective…

Weighted Schreier-type Sets and the Fibonacci Sequence

Hung Viet Chu, Zachary Louis Vasseur

For a finite set $A \subset N$ and $k \in N$ , let $ω_{k} (A) = \sum_{i \in A, i \neq = k} 1$ . For each $n \in N$ , define $$a_{k, n}\ =\ |\{E\subset \mathbb{N}\,:\, E…

On Schreier-type Sets, Partitions, and Compositions

Kevin Beanland, Hung Viet Chu

A nonempty set $A \subset N$ is $ℓ$ -strong Schreier if $min A ⩾ ℓ ∣ A ∣ - ℓ + 1$ . We define a set of positive integers to be sparse if either the set has at most t…
