Friday April 1

We will continue with exercises about morphisms of projective schemes


  • Work through example 6.4.1.
  • Work through example 6.4.2.
  • Exercise 6.4.C.  Different maps of graded rings can give the same morphism of schemes.
  • Exercise 6.4.D.
  • 6.4.E
  • 6.4.F.
  • 6.4.G.

Read the definition of a rational map, a dominant rational map, birational rational map, and what it means for schemes to be birational to each other.

  • Exercise 6.5.B.
