#4222 on tag 07HT by Dario Weißmann https://stacks.math.columbia.edu/tag/07HT#comment-4222 A new comment by Dario Weißmann on tag 07HT. Concerning the second paragraph of the proof. I suggest replacing "We will show this by induction ...." (till the end of the paragraph) by the shorter (and easier) direct calculation: The claim is clear for . Assume . Note that lies in for . Calculating modulo we have The claim follows.

#4219 on tag 07J3 by Dario Weißmann https://stacks.math.columbia.edu/tag/07J3#comment-4219 A new comment by Dario Weißmann on tag 07J3. Typo in the definition of the multiplication: has too many s

There is also an issue how the multiplication formula is displayed. It overlaps with the sidebar. Works fine in the pdf version though.

#4215 on tag 09LL by Frank https://stacks.math.columbia.edu/tag/09LL#comment-4215 A new comment by Frank on tag 09LL. It seems better to clarify the second property of graded tensor product: the in are different from those in the direct sum . In other words, here is only assumed to be no greater than . It seems better to choose different names for them.

#4214 on tag 03BX by David Holmes https://stacks.math.columbia.edu/tag/03BX#comment-4214 A new comment by David Holmes on tag 03BX. I came here to make the same comment as Wessel, but then I saw Wessel's comment, so I won't (maybe I just did...). So maybe count this as another vote for changing it??

#4212 on tag 02L3 by Sean Cotner https://stacks.math.columbia.edu/tag/02L3#comment-4212 A new comment by Sean Cotner on tag 02L3. Small point: after replacing S by f(X), you still use the assumption that S is affine. I think this can be fixed by instead base changing to an arbitrary affine open contained in f(X), after which the rest of the proof goes through.
