Event description: 

A well-known question of Gromov asks whether every one-ended word hyperbolic group G contains a surface subgroup. We consider the special case where G is the double of a free group F along the cyclic subgroup generated by an element w in F, and give various conditions on w under which Gromov’s question has an affirmative answer. This is joint work with Henry Wilton.
