Prerequisite: The course will assume a basic understanding of smooth manifolds (smooth maps, derivatives, differential forms) and algebraic topology (homology, cohomology).


Homework: Registered students are expectedly to regularly attend class and give a presentation on a topic related to the course. Please come talk to me to discuss the topic of your talk and to schedule a date.


Exam: This course does not have a final exam.


Academic honesty: As a University of Georgia student, you have agreed to abide by the Universitys academic honesty policy, A Culture of Honesty, and the Student Honor Code.
