A topological concept dual to compactness
the phrase "we define such a ``subspace'' by a predicate..." has convinced this classical mathematician not to read the rest of this post

Gabriel's theorem over a commutative ring
semisimple is most probably not a condition you're willing to impose, since a semisimple ring is a direct sum of fields.

why are motives more serious than “naive” motives?
I wish this question was tripartide: there are also the original Chow motives, and I'd like to know where they fit in visavis the above analogies.

Can monodromy be described by the same matrix for chosen generators in case of the same singularity type?
the description of which loops you've chosen has an ambiguity the size of a braid group

Computing Euler Charactistics of Line bundles on Hilbert Schemes of points on Surfaces
Using that stuff for this computation would be utterly absurd. The Hilbert scheme of two points is just the blowup of the diagonal of the symmetric product, which should give you an explicit handle on all the classes you need for RR.

If the direct image of f preserves coherent sheaves on noetherian schemes, how to show f is proper?
why should it even be separated? the map from the affine line with the doubled origin to the affine line seems like it ought to preserve coherent sheaves
