| Oct 17, 2016 at 5:02 | comment | added | Emma Previato | GOT IT! It's in David Eisenbud's Green's Conjecture: An Orientation (1991). The structure of the canonical ring of curves is known for genus less that or equal to 8 (at that time...) and also for smooth plane curves of any genus, so... it's overkill! John Mangual: You may be happy to see the abstract "tries to explain the attractiveness of canonical rings"... but the article is a little technical. Listen everybody, I had such a great experience here, it was my first time daring to post on MO and I enjoyed hearing back and learning the things that you found beautiful, thank you! | |
| Oct 12, 2016 at 4:13 | comment | added | Emma Previato | YES! thank you folks (really lots of interesting info), what I meant if "a la Green's conjecture" (I had notes 100 years ago but I can't find them; however, not about this specific curve; I vaguely recall there were remarks about a rank-2 bundle over the curve, must have been an extension of K_X). I wanted to know this ring as precisely as possible, to construct explicit bases of H^0(nK_X) (yep, I should have used additive notation to go with the word "divisor"); a related issue are of course higher Weierstrass points. | |
