 n\n\nDESCRIPTION\n\n\nEvery finitely presented group is the group of a clo
 sed 4-manifold. However\, 3-manifold groups are special. Part of the goal 
 of this conference will be to understand how special they are. The Wall co
 njecture  asserts  that  the  fundamental  groups  of  closed 3-man
 ifolds  are the same as groups which satisfy 3-dimensional Poincaré dual
 ity (PD(3) groups). Three-manifolds decompose along spheres and tori and t
 his translates to decompositions of their fundamental groups. There have b
 een very fruitful analogs of this decomposition for more general groups.\n
 The conference will focus on the structure of 3-manifold groups as well as
  structures on groups inspired by structures on 3-manifolds\, such as PD
  (3) groups\, relatively hyperbolic groups and buildings.\nWe will aim to
  address some of the following topics\, as well as new topics which may ar
 ise.\n\n\n 	Which of certain classes of groups\, for example limit groups\
 , are 3-manifold groups?\n 	Are hyperbolic 3-manifold groups determined by
  their profinite completions?\n 	How are the isometry groups of buildings 
 similar to three -manifold groups? What can the boundaries of hyperbolic b
 uildings tell us about these groups?\n 	Can one algorithmically decide if 
 a group is the group of a 3-manifold with boundary?\n 	When are relatively
  hyperbolic groups the fundamental groups of 3-manifolds?\n 	How can a sur
 face subgroup inside a group inform us about the structure of that group?\
 n 	Which group-theoretic properties of 3-manifold groups (such as residual
  finiteness) hold for more general classes of groups?\n\n\n\n \n\nSCIENTI
