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…

Higher Order Tsirelson Spaces and their Modified Versions are Isomorphic

Hung Viet Chu, Thomas Schlumprecht

We prove that for every countable ordinal $ξ$ , the Tsirelson's space $T_{ξ}$ of order $ξ$ , is naturally, i.e., via the identity, $3$ -isomorphc to its modified version. For the first…
