Maybe somebody can quickly help me out. I think I knew the answer to the following question, but now I must have gotten myself mixed up:
let F:Δ×Δ→Ab be a bi-cosimplicial abelian group and
diagF≃∫nΔn⋅Fn,•the corresponding cosimplicial group. From the Eilenberg-Zilber theorem we have that its cochain complex is the total complex of the double complex obtained from F
CdiagF≃TotCF.But what I need is instead such a statement for the end expression
∫nC(ℤ(Δn))⊗C(Fn,•)How is that related to TotCF•,•? Isn’t that isomorphic?
