Tree Pairs for Algebraic Bieri-Strebel Groups
Lewis Molyneux
We reintroduce a previously discovered method for constructing tree pair representations for Algebraic Bieri-Strebel groups, as well as demonstrate a class of higher order groups t…

The Sigma invariants for the Golden Mean Thompson group
Lewis Molyneux, Brita Nucinkis, Yuri Santos Rego
We use a method of Bieri, Geoghegan and Kochloukova to calculate the BNSR-invariants for the irrational slope Thompson's group . To do so we establish conditions under which t…
