| Jan 1 at 12:11 | comment | added | Z. M | @stupid_question_bot But the quoted definition tests regularity only after base change to an algebraic closure. I guess that the situation is similar to stacks.math.columbia.edu/tag/038X | |
| Jan 1 at 11:54 | comment | added | Z. M | @stupid_question_bot I am probably mistaken, but this definition seems to coincide with the usual definition: as you said, this definition works in the case that the base field $k$ is perfect, but the general case follows from the flat descent of smoothness along $k\to\bar k$. | |
| Jan 1 at 10:59 | comment | added | BernyPiffaro | @stupid_question_bot I am using Qing Liu's definitions and it is not required to work on a perfect field. | |
