Condition of pushward commutes with tensor product

Image
1 $begingroup$ Let $f$ be a morphism between schemes. Is there a sufficient and necessary condition on $f$ such that $f_*$ commutes with $otimes$ ? i.e. $$f_*Fotimes f_*Gcong f_*(Fotimes G)$$ for all coherent sheaves $F,G$ . In particular, I want to know that is it true for $f$ proper. algebraic-geometry schemes coherent-sheaves share | cite | improve this question asked Dec 17 '18 at 14:24 User X User X 334 11 $endgroup$ 1

Two whole notes next to each other in a bar? [duplicate]

Image
5 This question already has an answer here: What does it mean when two notes are stuck together? 4 answers How do you play two whole notes next two each other? They're not stacked on top of each other but rather one is slightly right of the first. It's in 4 4 time and so that means 1 whole note should take the entire bar. So when should I play the second whole note? There's also a tie that goes into the next bar which has the same two notes but they are now stacked on top of each other piano notation sheet-music share | improve this question
