comment What if $\operatorname{char}\mathbb{K}$ is not $0$ or if $\mathbb{K}$ is not algebraically closed? (Nullstellensatz)
Thank you! So I guess I only need to know what happens if the field is both of positive characteristic and it is not algebraically closed!

comment Projective dimension of the residue field of a noetherian local ring.
I think I don't get your hint. The residue field has finite injective dimension and I would like to prove that also its projective dimension is finite...

comment An exercise about separable algebras
Ok, thanks.. can I say $A_P=A\otimes_R R_P$ for all $P\in Spec(R)$? or something like that?
