    I addede a paragraph at Poincaré duality about the generalizations, and created the entry (so far only descent bibliography) Grothendieck duality; the list of examples expanded at duality. All prompted by seeing the today’s arXiv article of Drinfel’d and Boyarchenko.

    I just threw in a statement at Grothendieck duality, because I found looking at 12 references a little daunting.

    Yes. Sorry, I just glanced at one of the sources and for some reason it used that term.
