2. Many properties of projective schemes extend to this context.
3. For example, every quasi-projective scheme over a Noetherian ring has the resolution property.
4. For example, there exist an analog of the celebrated Serre duality for noncommutative projective schemes of Artin and Zhang.
5. The "'cohomological Brauer group "'of a quasi-projective scheme over a commutative ring ).
6. It's difficult to find projective scheme in a sentence. 用projective scheme造句挺難的
7. Since the " D " ( " & phi; " ) form an open cover of " X " the projective schemes can be thought of as being obtained by the gluing via projectivization of isomorphic affine schemes.
8. Gieseker showed that there is a coarse moduli scheme for surfaces of general type; this means that for any fixed values of the Chern numbers " c " 1 2 and " c " 2, there is a quasi-projective scheme classifying the surfaces of general type with those Chern numbers.
9. Similarly, if " R " is a graded ring and " X " is the Proj of " R ", then any graded module defines an " O " " X "-module in a natural way . " O "-modules arising in such a fashion are examples of quasi-coherent sheaves, and in fact, on affine or projective schemes, all quasi-coherent sheaves are obtained this way.
