DESCRIPTION:Matt Feller\, University of Virginia\nThe Joyal model structur
 e on simplicial sets has been an important setting for developing the theo
 ry of higher category theory. The fibrant objects are the quasi-categories
 \, a model for (∞\,1)-categories\, which have a straightforward characte
 rization: they are the simplicial sets with lifts of inner horn inclusions
 . However\, so far in the literature there has been no such characterizati
 on of the fibrations in terms of a countable set of concrete maps. We give
  a conjecture of such a characterization\, describing a class of ``special
  horn'' extensions. We use Cisinski's theory to build a model structure wh
 ose fibrant objects are simplicial sets with special horn extensions.
