| Oct 27, 2017 at 5:02 | comment | added | Geordie Williamson | I had fascinating conversations with Neeman about this. See arxiv.org/pdf/1406.7599.pdf. I am given to understand that the adjoint (which Neeman denotes $f^{\times}$) exists in great generality (e.g. separated, Noetherian, finite type is enough), and is technically very useful. The main issue is that it is not "local", but otherwise is quite well behaved. But it is much better to read the paper! | |
