| Aug 20, 2020 at 10:29 | comment | added | Jan Grabowski | If you want an approach to noncommutative projective geometry, this survey arxiv.org/abs/math/9910082 of Stafford-Van den Bergh describes work following the philosophy due to Artin-Tate-van den Bergh of using a category of graded modules modulo torsion to stand as a noncommutative projective space. This ultimately relies on a noncommutative version of Serre's theorem, which in the commutative setting says that this category is equivalent to that of (quasi-) coherent sheaves. I know this doesn't quite answer your question as posed but hope it's helpful. | |
