The geometry of twisted conjugacy classes in wreath products
Jennifer Taback, Peter Wong
We give a geometric proof based on recent work of Eskin, Fisher and Whyte that the lamplighter group has infinitely many twisted conjugacy classes for any automorphism $\vp$…

Twisted conjugacy classes for polyfree groups
Alexander Fel'shtyn, Daciberg Gonçalves, Peter Wong
Let be a finitely generated polyfree group. If has nonzero Euler characteristic then we show that has a finite index subgroup in which every automorphism has infin…
