Abstract
It is known that splittings of finitely presented groups over 2-ended groups
can be characterized geometrically. We show that this characterization does not
extend to all finitely generated groups. Answering a question of Kleiner we
show that the Cayley graph of the lamplighter group is coarsely separated by
quasi-circles.
