Textbook: Topology, Second Edition by James R. Munkres. ISBN: 0-13-181629-2

Class meets Tuesday and Thursday, 10:30 to 11:45 in the Smokler Center Library.

**Office hours** are Thursday, 11:45-12:45. (Krieger 421.)
This is right after class, so if you want to come to office
hours, you arrange that in class, or I won't be there.
You can always email me with questions or to set up a meeting
if the office hours don't work for you or aren't enough.

In addition, you should all know about the **math department
help room** that is open nearly all day and most evenings during
the week. It is in Krieger 213.
Your grader will be there in the help room on Wednewsdays, 3-5pm, but
most in the help room can help you with topology.

Students in this course are assumed to be (the equivalent of) serious math majors and will be treated as such. This is not an introduction to proofs course but assumes all students have had such a course already. Each week there will be a reading assignment and homework. Each class there will be a test and graded group work.

**
All students must attend every class and maintain a high level
of consciousness during the entire class. You will have something
serious to do during the entire class, every class (except the
first one on Jan 29).
**

The **reading assignments** are already set for the entire course
and are at the bottom of this website.

The pattern for the course is:

**Tuesday:**
Your homework is due at the start of class on Tuesday. A test
will be given immediately. The test will cover the material
that you read for the homework just handed in.
There will probably
be two problems, one from the homework just handed in, and
one from the sections the homework was based on. I reserve
the right to ask whatever I want though.

**More Tuesday:**
I will give a very short lecture on the material you are
about to read for Thursday so you'll know the high points
to look out for.

**Tuesday Continued:**
After the test, I will assign small groups to work on a sequence
of problems. These problems will be from the material you
read for the homework you just handed in, so you should be
really good at it.
The group will
write them up to be handed in at the end of the class for the
whole group. The whole group will get the same grade on this.
The groups will vary day to day.

**Thursday:** I give you a quiz when you walk into class.
The primary purpose is to see if you have done the reading.
It will cover really basic things like
definitions and statements of theorems. No understanding is
required to do well on this, but I want people prepared to work,
not read, when they come to class on Thursday.
You can teach a 10 year old to do this perfectly, so
to make it college level, I'll add a serious topology content problem
to the quiz.

**Thursday continued:**
You will be assigned to small groups to work on
problems. These problems will be for the reading you were
just quizzed on. As above:
The group will do as many of them as they can and
write them up to be handed in at the end of the class for the
whole group. The whole group will get the same grade on this.
The groups will vary day to day.

**More Thursday:** I will post the homework on the next reading assignment
sometime before the end of the day on Thursday.

**Terminology:**
We call the Thursday exam on reading (plus some content) a "quiz" and the
Tuesday exam on content a "test."

**Grades, homework, and stuff:**
You have homework. Two or three problems of my choice, unknown to you,
will be graded by the TA.
Also, on Tuesday and Thursday
you will be working problems in groups most of the class.
Some of these problems will be graded.
There are the two exams each week.
All in all, there
are lots of things that get graded that will go into your
grade. How they will all be
weighted will get worked out during the semester. For example,
you will probably get graded on more problems worked in groups
than individually, but your individual work will probably
dominate the grade.

**Group work:**
You are welcome to, even encouraged to, work together on
homework, but you must write up your own homework. If you
write up your own, it will not be the same as that written
up by students you worked with.

**The syllabus**, subject to, but not likely to, change.

The first week is a bit awkward. You won't know anything on the first day of class, Jan 29, so you really can't be expected to do anything. The first chapter of the book (all 74 pages of it) are stuff I usually skip at the start of the course as it is mostly about basic terminology, notation, and elementary background. In general, I feel I should be able to assume this. However, this year I've decided to give the class a week to read this stuff.

So, what I'm going to do is give a long long quiz on sections 1.1 to 1.4 on Thursday, the second class, Jan 31, to see if you have read the material. Similarly, I'll give a long long quiz on sections 1.5 to 1.11 on Tuesday, Feb 5. This will give all of you a large number of points at the beginning of the course. It will also seriously penalize anyone who decided they didn't need to read the chapter I have so generously and unnecessarily given you a week to read. The first chapter amounts to reading assignment # 0. If I find any content in those chapters worth asking you about, I might slip content questions on those quizzes.

**Last day of class.** Still doing group work. And, of course,
a content test just for sport.

There is no final exam.
