This is the page with specific information for Week 1 of our Algebraic Geometry Graduate Reading Course

Discussion Leader: David

Schedule

Week one

• For 9/3: Read & be prepared to discuss 2.1 & 2.2
• For 9/6: Read & be prepared to discuss 2.3

Homework

No homework due until 9/8

Questions

• In 2.3, the universal properties Ravi defines for localization, etc are also referred to as "initial". In what sense are they initial? We think we identified that these correspond to initial objects in some crazy comma category, but is there a better way to think about that?

Comments

• 2.2B: We were a little confused with the phrase "invertible elements of Mor(A,A)" - we assumed this meant elements with left and right inverses.
