# A reference for Calculus of Functors for Model Categories

I am wondering where I might look to see what has been done in terms of Calculus of Functors for more general weak equivalences and Model Categories.

I am at least aware of some of the extended definitions of the main concepts in Calculus of Functors to weak equivalence such as homotopy limits, but I was wondering if a document existed that worked through the basic of COF in this setting.

I am aware also of Lurie's work here.(Thanks Harry for pointing this out.)

I don't think I agree with the addition of those two tags, but it matters little to me, so I will leave them. –  B. Bischof Sep 16 '10 at 20:02

In Calculus III and its predecessors I studied functors from Top to Top and a few related cases. The ideas clearly generalize to functors $C\to D$ between model categories satisfying some pretty weak axioms, but I did not try to find the right axioms, and I don't think anyone has ever written anything definitive about that.

The paper mentioned by Tilson takes the ideas in a somewhat different direction, I think: it's about treating the categories of functors themselves as model categories and finding Quillen adjoint pairs that refine my ideas.

@Tom This is exactly what I was looking for. I was hoping to "model"(ha ha) the style of the Goodwillie Calculus on Homotopy equivalences, to more general weak equivalences on some model categories. Thanks! –  B. Bischof Sep 16 '10 at 15:26
