Plan, exam etc.

The exam in MAT4530 will be on Monday June 10, and the last lecture will be Thursday May 30. 

I have now started Chepter 3 - Cohomology - and today I finished section 3.1, containing the basic definitions and the part of the theory that is analogous to homology.   The main new structure in cohomology is the cup product (section 3.2), and I will start discussing that on Thursday May 16.
