| Feb 5, 2012 at 23:12 | comment | added | Jim Humphreys | @Donu: That might be a good rationale for the terminology, but in any case the section starts out with the definition of "t-category" as a special type of triangulated category which is natural for the theory of perverse sheaves. It would be interesting to know the viewpoints (possibly divergent) of the three authors, one of whom probably did the major writing here (in French). | |
