Geometric Topology


Math 99r - 3:00 - 6:00 Mondays - room 530 SC
Harvard University - Fall 2003

Description. How is a sphere different from a torus? A square-knot from a granny knot? In this tutorial we will discuss topology in dimensions one, two and three, with an emphasis on problems and examples.

Prerequisites: Algebra and topology. (Math 122 and 131). Some complex analysis (Math 113) may be useful.


Instructor: Curtis T McMullen
