About Topology

Goals

I have three main goals for this course. First, you will learn about three areas of topology: point-set, geometric, and algebraic. Point-set topology lays the foundation, it sets up the language used in all areas of topology as well as fields such as analysis and dynamics. Geometric topology studies how spaces are built out of complexes (glorified triangles!), and properties of spaces such as Euler number, genus, etc. Finally, algebraic topology relates topological spaces to groups and other algebraic objects. Group theory can then lead to an understanding of the nature and behavior of a topological space.

A second goal is to help you refine your ability to read and write proofs. Theorem/proof writing is the method by which high-level mathematics is communicated. In addition, mastering the logic and language that are involved in proof-writing is a skill that will certainly help you in whatever career you choose to have after you leave St. Olaf.

Finally, you will be asked to do a project on any one of a number of topological topics. Doing research and then presenting your findings is another skill that will help you in your future career.

Prerequisites

You need to have taken either ERA or Abstract Algebra. If you have not taken algebra, I will teach the group theory necessary for understanding the algebraic topology we will cover.

Class Structure

As with most 300-level courses, topology will be driven by lectures. There will be some opportunities for in-class problem solving as well as presenting. Most exciting of all will be the days when we get to play with Fisher Price toys, softballs and donuts!

Requirements

Your final grade will be based on the following: homework assignments, a final project, and three exams.

Homework Assignments

Homework is likely to be assigned weekly. I'm guessing that it will be due on Tuesdays.

Project

We will end the semester with presentations of projects. Early in the semester I will give you some topic ideas, or you may choose one of your own. The only stipulation is that the project relate to topology in some tangible way.

Throughout the semester I will ask about your progress on the project. First I will ask for your idea and sources, later I will want an outline, a first draft, etc. Dates for these assignments will be determined later.

Exams

There will be three take-home exams during the semester. Dates for these will be determined later.

Evaluation

Your final grade will be determined by:

Homework 20%
Project 20%
3 Exams 60%

Miscellaneous Items

Participation

In order for this particular course to be successful, I hope that you all will fully participate in the class activities. I would like you to

Getting Help

As you might guess, the math clinic does not provide support for topology students. Your only hope for help is me. Check my office hours for official times I'll be available during the semester, or simply swing by my office when you're in the neighborhood and see if I have time to answer a question or two.

Honor Code

There is an honor system by which all St. Olaf students must abide. I expect you to follow the system in conjunction with my particular course, homework and exam guidelines written throughout this document and discussed in class.

Make-up Policy

If you are absent because of an extra-curricular activity, homework and exams should be submitted early rather than late. If you are sick or have some other sort of emergency, you must notify me immediately. In such a (legitimate) case, homework will be due two days after you return to class and exams must be made-up within one week. Note that a make-up exam will potentially be harder than the original exam.

E-Mail

I expect all of you to read your e-mail on a regular basis. From time to time, I will send you notes regarding homework, exams, etc. You are responsible for reading these notes.
