 ">Characterizing slopes for torus knots and hyperbolic knots</a>\nby Dunca
 n McCoy (Université du Québec à Montréal) as part of McGill geometric 
 group theory seminar\n\n\nAbstract\nA slope $p/q$ is a characterizing slop
 e for a knot $K$ in the $3$-sphere if the oriented homeomorphism type of $
 p/q$-surgery on $K$ determines $K$ uniquely. It is known that for a given 
 torus knot all but finitely many non-integer slopes are characterizing and
  that for hyperbolic knots all but finitely many slopes with $q>2$ are cha
 racterizing. I will discuss the proofs of these results\, which have a sur
 prising amount in common.\n
