| Apr 17, 2022 at 4:18 | comment | added | Kapil | One may perhaps formulate a modification (pun intended!) to the question. Given a reduced irreducible algebraic space $\mathcal{X}$ is there a morphism to a scheme $Y$ such that the function field of $Y$ is the same as the function field of $\mathcal{X}$. Is there a theorem of Artin on this question? | |
