Lifting subgroups of $PSL_{2}$ to $SL_{2}$ over local fields

Naomi Andrew, Matthew J. Conder, Ari Markowitz +1

Let $K$ be a non-archimedean local field. We show that discrete subgroups without 2-torsion in $PSL_{2} (K)$ can always be lifted to $SL_{2} (K)$ , and provide examples…

Discrete and free two-generated subgroups of $S L_{2}$ over non-archimedean local fields

Matthew J. Conder

We present a practical algorithm which, given a non-archimedean local field $K$ and any two elements $A, B \in S L_{2} (K)$ , determines after finitely many steps whether or not the…

Further Rigid Triples of Classes in $G_{2}$

Matthew Conder, Alastair Litterick

We establish the existence of two rigid triples of conjugacy classes in the algebraic group $G_{2}$ in characteristic $5$ , complementing results of the second author with Liebeck a…
