Jun 10, 2020 at 6:56 | comment | added | Lennart Meier | @k.j. The citation is indeed wrong, but the statement that an injective morphism of rings induces a dominant morphism on their spectra is still true. See for example math.stackexchange.com/questions/389036/… for a proof. | |
Jun 10, 2020 at 2:48 | comment | added | k.j. | In the proof of lemma 2.5.(3) of your note, using Stack Project Tag0CC1, you conclude that $\operatorname{Spec}R \to \operatorname{Spec}R_0$ has the dense image. But this proposition assumes that $R$ is an integral domain. Why do we use this for general $R$? | |
