Some embeddings between symmetric R. Thompson groups

11 Feb 2020  ·  Aroca Julio, Bleak Collin ·

Let $m\leq n\in \mathbb{N}$, and $G\leq S_m$ and $H\leq S_n$. In this article we find conditions enabling embeddings between the symmetric R. Thompson groups $V_m(G)$ and $V_n(H)$... When $n\equiv 1 \mod(m-1)$ and under some other technical conditions we find an embedding of $V_n(H)$ in $V_m(G)$ via topological conjugation. With the same modular condition we also generalise a purely algebraic construction of Birget from 2019 to find a group $H\leq S_m$ and an embedding of $V_m(G)$ in $V_n(H)$. read more
