comment Vanishing of local cohomology groups
Not entirely... You reduce to $Ext^i(A,A)$ because you make the Ext commute with the direct sum? This does not work in general, right? Anyway, is it obvious that $Ext^i(A,A)=0$ - by Koszul computation, for example?

I actually don't know about Matlis duality. I was mentioning just Grothendieck's duality. Can you elaborate a little bit? Do you have a reference?

I haven't noticed that there was a misplaced point. Fixed.
