Existence of functorial (K-)flat resolutions?
The construction of the complex S^\bullet corrected by adding contractible two-term complexes (to make S^\bullet indeed a generator of Ch(X)).

@C00 Functorial resolutions by infinite-dimensional vector bundles, yes. It will be not just direct sums, but transfinitely iterated extensions of your original generating vector bundles.

F^\bullet replaced by G^\bullet to avoid ambiguity

$\operatorname{Ind}(C^I) = \operatorname{Ind}(C)^I$?
@varkor I put the files of Ulmer's preprint on my homepage at math.cas.cz/~positselski (rubric "Old manuscript file share"). Please let me know if you have any problem downloading them.

@varkor Yes, I have a copy I got from Rosicky yesterday. It is a bit bulky (four .zip files, several megabytes each). If you are not in a hurry, I will post the files on my homepage when I come to my office, and give the link here.

Definition of the symmetric algebra in arbitrary characteristic for graded vector spaces
What does $(-1)^{|x||y|}$ mean when $|x|$, $|y|\in G$ and $G$ is a finite abelian group?
