DESCRIPTION:Boundaries of hyperbolic spaces have played a key role in low 
 dimensional topology and geometric group theory. In 1993\, Paulin showed t
 hat the topology of the boundary of a hyperbolic space\, together with its
  quasi-mobius structure\, determines the space up to quasi-isometry.   One
  can define an analogous boundary\, called the Morse boundary\, for any pr
 oper geodesic metric space. I will discuss an analogue of Paulin&rsquo\;s 
 theorem for Morse boundaries of CAT(0) spaces.  &nbsp\;  (Joint work with
