An object c of T is compact if Hom(c,-) commutes with coproducts, i.e. every map from c to a coproduct factors through a finite sub-coproduct. T is compactly generated if there exists a small suspension closed set G of compact objects such that Hom(g,X) = 0 for all g in G iff X=0 for any object X of T. Comments are not really the ideal place for this - but it works for the moment I guess. | |
