I want to ask a stupid question. I wonder whether following morphism exists in general Let I be an infinite set. i belongs to I Hom(A,colimBi)--->limHom(A,Bi) and ...
Are filtered colimits exact in all abelian categories? In Set, filtered colimits commute with finite limits. The proof carries over to categories sufficiently like Set (i.e. where you can chase ...
(1) What are some good references for homotopy colimits? (2) Where can I find a reference for the following concrete construction of a homotopy colimit? Start with a partial ordering, which I will ...
