The purpose of the lectures is to supply an creation to contemporary advancements within the concept of sophistication teams and Picard teams. The strategies hired come from the 3 major parts: algebraic quantity thought, illustration thought of algebras and orders, and algebraic $K$-theory.

Then QH ∗ (X) is in Un if and only if Ωn+1 X is BZ/p-local. Bill Dwyer and Clarence Wilkerson have shown that the case n = 0 holds for arbitrary spaces. However, our methods rely so deeply on the H-structure that we still don’t know if one should look for a positive or negative answer to our last question. 6. Let X be a connected space such that TV H ∗ (X) is of finite type for any elementary abelian p-group V , and let n ≥ 1. Is it true that QH ∗ (X) is in Un if and only if Ωn+1 X is BZ/p-local?

Similarly, a map ψ : V → W is called cellular if it is of the form of the canonical augmentation map for the cellularization functor in the relevant category: cellA W → W. It is not hard to see that a map is cellular if and only if it induces an equivalence map∗ (V, V ) → map∗ (V, W ). In that case V = cellA W is equivalent to cellV W. Given the above concepts, most of the following problems-conjectures are elementary in their formulations. But some have proven surprisingly difficult to confirm or negate.
