Dr. Eugen Hellmann
E-mail: hellmann (add

Monday 12-14h, Thursday 10-12h, Kleiner Hörsaal, Wegelerstraße 10
First lecture: 07.04.2014


The lecture builds on the course Algebraic Geometry I and continuos the study of schemes and their properties. The provisional schedule includes:

  • Global and local properties of morphisms:
    • global properties: affine and projective morphisms; separated and proper morphisms; the valuative criteria;
    • local properties: ètale, smooth and unramified morphisms; infinitesimal lifting criteria
  • Formal schemes
    • basic definitions; completion of schemes along closed subschemas
    • coherent sheaves on formal schemes
    • formal GAGA
  • Cohomology of (quasi-)coherent sheaves
    • derived functor cohomology and Čech cohomology
    • Higher direct images; cohomology and base changes; applications
    • Serre duality

Exercise sessions

There are weekly exercise sessions accompanying the lecture. It is necessary to attend the exercise sessions and hand in the exercise sheets in order to participate in the final exam.
The exercise sessions take place on Fridays, 10-12h, Romm 0.008.
