Felix Klein famously said "Given a manifold with its associated transformation group, one should investigate those structures of the manifold that have properties which are invariant under the transformation group." Conversely, it turns out that the algebraic properties of a group are often reflected in the geometry of spaces they act on. We will try to understand groups by examining their inherent geometry.

Homework and Class Project:
There will be 4 homework assignments and a longer assignment called the Class Project. The class project can be chosen from the projects given in the textbook (after discussing with me) or any topic related to in class dicussions. The Class Project has a written and presentation component. Students are encouraged to work together on the homework problems but have to write their own solutions.
- Problem Set I, Due September 28, Chapters 1, 2 and 3.
- Problem Set II, Due October 19, Chapters 4 and 5.
- Problem Set III, Due November 16, Chapters 7 and 9.
- Problem Set IV, Due December 7, Chapters 13, 15 and 16.
Midterm and the Final Assessment
You should read the relevant parts of the textbook, ideally before the lectures in class on the same material, and attempt most of the exercises in the textbook. Make sure to ask questions during class. Questions slow the pace and give everyone time to think about what is being said. Use the office hours, talk to each other and talk to the TA. The more time you spend with the material the more intuitive the concepts of the course will become. Try to find a topic for your Class Project early.
