Prerequisites

  • Some knowledge of algebra and point-set topology at the level of Math 121.
Homework

There will be weekly problem sets; see the class schedule.  Homework is due on Mondays, although there may be some exceptional weeks.  The problem sets count for a large percentage of your total grade (approximately 70%).  You may work with others or consult other textbooks, but the homework you turn in must be written by you, in your own words, and you must cite your sources used and your collaborators!

Final examination

There will be a take-home final.  This will be approximately 30% of your final grade.
 

WARNING:  The course syllabus provides a general plan for the course; deviations may become necessary.
