DESCRIPTION:Let G be&nbsp\;a torsion-free Gromov hyperbolic group\, whose 
 boundary at infinity is an n-dimensional Sierpinski space. I&#39\;ll expla
 in why\, if n>4\, the group G is in fact the fundamental group of a (uniqu
 e) aspherical (n+2)-manifold with non-empty boundary. Time permitting\, va
 rious related results will also be discussed. This is joint work with Bena
  Tshishiku.
