Familiarity with some concepts from 18.702 such as commutative rings, modules, and manifolds is very helpful.

Subject Matter

The class was very theoretical.

Students mentioned that there are many interesting applications to algebraic topology and this class covers the bases well and is useful for those hoping to explore the field further.

Course Staff

Professor Hahn was described as very approachable and engaging.

Lectures

Lectures were described as somewhat slow and easy to follow.

Lectures focused on examples and told an interesting story.

Problem Sets

Problem sets were long, though were bi-weekly.

Problems were generally described as fun and challenging. They helped solidify an understanding of the material.

Exams

There were no exams besides the final.

Resources

Lecture notes by Prof. Haynes Miller were most useful.

Allen Hatcherâ€™s Algebraic Topology was used, but did not follow the class material as closely.
