Affine and proper morphisms

  • Ulrich Görtz
  • Torsten Wedhorn


In this chapter, we will study properties of morphisms of schemes which distinguish important subclasses of morphisms. The emphasis in this chapter is on properties that are not local on the source. We start with a relative version of being affine and then study finite and quasi-finite morphisms.
