Page content
1) Cohomological characterization of ampleness.
2) Every quasi-compact scheme has a closed point.
The rest is not part of exam syllabus.
3) Higer derived pushforwards of a coherent sheaf along a proper morphism is coherent (no proof).
4) Euler characteristic.
5) Riemann-Roch on curves which are proper over an algebraically closed field.
6) Serre duality (no proof)
7) Consequences of Riemann-Roch.
8) A morphism separating points and tangent vectors is a closed embedding.
9) Any regular, integral curve which is proper over an algebraically closed field is projective.
