From: Topos8@aol.com (Carl Futia) Around the same time the group surrounding Grothendieck at IHES had informally developed a non-recursive definition of strict n-category similar to what is used today.
...prompting the question of whether x-categories for noninteger real x have been looked at. Presumably an early question here would be whether the spaces of fractional dimension that have already been studied depend on any geometric properties beyond those of n-categories. In particular what restrictions must one accept in order to have a coherent notion of a 1.5-category? Vaughan Pratt
