DESCRIPTION:A trivalent triangle group is a triangle of groups with the tr
 ivial face group and edge groups isomorphic to Z/3Z. In this talk\, I will
  introduce the weighted L2-cohomology of Coxeter groups originally defined
  by Davis\, Dymara\, Januszkiewicz and Okun and use it to show virtual fib
 ration and consequently incoherence of certain trivalent triangle groups a
 cting on hyperbolic buildings.
