DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSUGGT/13/">
 Retracts in free groups</a>\nby Ilir Snopce (Rio de Janeiro) as part of Oh
 io State Topology and Geometric Group Theory Seminar\n\n\nAbstract\nA subg
 roup R of a group G is said to be a retract of G if there is a homomorphis
 m r : G → R that restricts to the identity on R. I will talk about retra
 cts in free groups. In particular\, I will discuss the following question 
 raised by Bergman: Let F be a free group of finite rank and let R be a ret
 ract of F.  Is it H ∩ R is a retract of H for every finitely generated s
 ubgroup H of F? \n\nThis talk is based on a joint work with Slobodan Tanus
 hevski and Pavel Zalesskii.\n
