DESCRIPTION:Title: The Hrushovski property for hypertournaments and profini
 te topologies \n\nAbstract: During the talk I will discuss a problem conce
 rning extensions of partial isomorphisms of finite tournaments and its equ
 ivalent form\, which is a problem about the pro-odd topology on the free g
 roup. The pro-odd topology is the refinement of the pro-finite topology wh
 ere we take only the normal subgroups of odd index as the neighborhood bas
 is of 1. The problem concerns a characterization of those finitely generat
 ed subgroups of the free group which are closed in the pro-odd topology. I
  will discuss a positive answer for cyclic subgroups and a negative answer
  for a generalized version of this question. Joint work with J. Huang\, M.
  Pawliuk and D. Wise.\n	 \n
