DESCRIPTION:Title: From Stalling's Theorem to Morse boundaries.\n\nAbstract
 : Every finitely generated group G has an associated topological space\, c
 alled a Morse boundary. It was introduced by a combination of Cordes and C
 harney--Sultan and captures the hyperbolic-like behavior of G at infinity.
  In this talk\, I will motivate the research on Morse boundaries in severa
 l steps. First\, I will explain Stalling's theorem -- a fundamental theore
 m in geometric group theory. Afterward\, I will explain an analogous state
 ment for so-called Gromov boundaries of Gromov-hyperbolic groups. As Morse
  boundaries generalize Gromov boundaries\, this raises the question as to 
 whether one can generalize this statement to Morse boundaries. Finally\, w
 e will see the relationship between a result on Morse boundaries of graphs
  of groups and this problem. Results presented are joint with Elia Fiorava
 nti.\n
