Jan 27, 2023 at 5:12 comment added Hacon If your doubt is about quasi-coherent $O_X$-modules vs, $O_X$-modules then you are correct and this is incorrect as stated in Mukai's paper (he is aware of this) see mathoverflow.net/questions/243202/…
Jan 23, 2023 at 9:42 comment added Gro-Tsen @CraniumClamp This particular linguistic point occurred a number of times on MathOverflow already, but “I have doubts” is sometimes used, esp. by non-native English speakers, to convey their misunderstanding rather than their belief that there is a mistake in the reasoning. (Not being a linguistic prescriptivist, I will not endeavor to discuss whether they're “right” or “wrong” to use this phrase in this sense.)

Jan 22, 2023 at 7:58 comment added Doug Liu Dear @Clamp, Thanks for your comment! First of all, the flat base change theorems that I have seen are about "quasi-coherent" modules. But in Mukai's case, $Mod(O_X)$ is the category of all $O_X$-modules. Secondly, I don't know how flat base change helps this problem when $F$ is NOT $O_{X\times Y}$. For these reasons, I keep my doubts
