Talk:Derivator

Todo

 * Discuss open and closed immersions of functors of indices
 * Look at recollement in SGA 4 IV.9 - http://www.normalesup.org/~forgogozo/SGA4/04/04.pdf
 * Add definition of derivator with explanation of each axiom
 * Chapter 3 has new definitions for cohomology of diagrams in Hotab and relations to classical cohomology
 * Look at deriving adjoints, https://stacks.math.columbia.edu/tag/0FNC
 * Derived colimits https://stacks.math.columbia.edu/tag/0A5K
 * Derived limits
 * Also checkout cotangent complex book for more techniques, maybe they are useful for derivators with indices in ordinals — Preceding unsigned comment added by Wundzer (talk • contribs) 18:13, 1 May 2020 (UTC)
