Confined subgroups of Thompson's group $F$ and its embeddings into wobbling groups

Maksym Chaudkhari

Published 2018-09-13Version 1

We obtain a characterisation of confined subgroups of Thompson's group $F$. As a result, we deduce that orbital graph of a point under action of $F$ has uniformly subexponential growth if and only if this point is fixed by the commutator subgroup. This allows us to prove non-embeddability of $F$ into wobbling groups of graphs with uniformly subexponential growth.
