# Open problems in “Algebraic geometry by robin hartshorne”

Hi,

Is there a list of which of the open problems in algebraic geometry by robin hartshorne are still open ? (I searched the internet and didn't find one)

Thanks from advanced, Matan Fattal

Do you mean open problems mentioned in Hartshorne's book or conjectures that he made? –  Felipe Voloch Aug 5 '11 at 20:23
problems mentioned in hartshornes book (the ** excercises) –  Matan Fattal Aug 5 '11 at 20:26
I think all of them are still open. –  S. Carnahan Aug 5 '11 at 23:43
do you know of any refernce ? –  Matan Fattal Aug 5 '11 at 23:55
No, but you can look up relevant words on Google Scholar. Hartshorne has said that his entire mathematical career was structured around trying to prove the set-theoretic intersection conjecture (I.2.17d), and it still seems to be open. The ArXiv gets "proofs" of the Jacobian conjecture (I.3.19d) reasonably often. If it were proved, we wouldn't see that much activity. Also, if either were solved, I imagine people would talk. Are there other problems that I missed? –  S. Carnahan Aug 8 '11 at 3:36
