Ma 151a - Algebraic topology 1; Fall 2009
Instructor: Danny Calegari
Grader: Yi-Chih Chiu (email ycchiu)
MWF 2-3 257 Sloan
Grading policy:
Homework is posted on the web at regular intervals. This homework is due at 2 pm (outside the office) on the day indicated. There will be a midterm
(in place of one of the homework assignments) and a final. The exams together will be worth 50% of the grade, and the homework 50%. The only difference
between an exam and a regular homework is that collaboration is not allowed.
Description of course:
This is the first course in the year-long graduate
sequence in topology. The main topics covered are fundamental
group, covering spaces, and homology. This comprises roughly
Chapters 0-2 of the required text, which is
Algebraic
Topology by Allen Hatcher. The book is available online, which is
very convenient, but it is priced so reasonably that it would be foolish
not to buy a copy.
There are not many prerequisites beyond some point-set topology,
undergraduate analysis, and a certain amount of mathematical
maturity. The Caltech class Ma 108a would suffice as background.
