| Feb 9, 2018 at 2:32 | comment | added | user113393 | @JasonStarr Thanks. I'm not sure I understand the last part of your comment, though. I'm not asking about any adequate equivalence relation inducing an étale equivalence relation on Chow varieties. The question is really about the following general construction about monoid objects in schemes: I included the general question at the bottom | |

| Feb 8, 2018 at 23:07 | comment | added | Jason Starr | This is only a note about symbols, not about your question. Most algebraic geometers use the symbol $A_r(X)$ to mean the Chow group of $r$-dimensional cycles modulo rational equivalence. The equivalence relation of rational equivalence is very far from being an etale equivalence relation, e.g., think of zero cycles on a K3 surface of the form $(p,q)\mapsto \underline{p}-\underline{q}$. | |
