DESCRIPTION:Steve Bennoun (UBC)\nThe notions of weak bialgebra and weak Ho
 pf algebra were introduced by Böhm\, Nill and Szlachanyi as generalizatio
 ns of the well-known notions of bialgebra and Hopf algebra. One important 
 result about weak bialgebras is that any fusion category is equivalent to 
 a category of modules over a weak Hopf algebra.\nIn this presentation I wi
 ll start by defining weak bialgebras and weak Hopf algebras. I will then b
 riefly present some examples and basic properties. Next\, generalizing res
 ults of Hayashi for bialgebras\, I will explain under which hypotheses one
  can construct the weak bialgebra of fractions of a given weak bialgebra. 
 I will moreover discuss the relationship between the weak bialgebra of fra
 ctions and the weak Hopf envelope.
