A hyperbolic free-by-cyclic group determined by its finite quotients
Naomi Andrew, Paige Hillen, Robert Alonzo Lyman +1
We show that the group is profinitely rigid amongst free-by-cyclic groups, providing the first example of a hyperbolic free-by-c…

Low complexity among principal fully irreducible elements of Out()
Naomi Andrew, Paige Hillen, Robert Alonzo Lyman +1
We find the shortest realized stretch factor for a fully irreducible and show that it is realized by a "principal" fully irreducible element. We also show…
