**Warning **: The x-hours will be used and in fact be the most
important part of the class (see below) so make sure the time is good for
you!

**Text**: *Basic Topology*, by M. A. Armstrong

**Grade**: Your grade will be determined as follows: homework and
presentations will be 50% of your grade, and
two exams will constitute 25% each.

**Homework**: Homework
will be posted on the "x-session day" and
due by the following "x-session day". The assignments can be found in
the
Homework Log. You will be given a relatively
small homework load (about 4 problems per lecture) which you will be
expected to do completely. One of the goals of this class is to learn to
articulate and write up your
solutions carefully. Each week at x-session you (or a group of you) will
be given 10 minutes to write a randomly selected solution on a
transparency, and then given the opportunity to present the solution to
the class (Technicalities: (a) the problems will be from the previous
week's assignments so you will have plenty of time to receive help
(b) not being able to demonstrate a well thought out attempt at a problem
you are asked to present is the worst thing that can happen to you
grade-wise in this course.) At this point we will discuss the result
together and by the next day you will be expected to turn in an accurate
version of the solution which will be posted on the web site.
You will be allowed to form homework groups of size 1, 2, or 3. It is
each group member's responsibility to think about and eventually
understand a solution to all the assigned homework problems.
(To reward students who take this seriously: keep a version each
problem ** written up by yourself **,
and at the end of the quarter I will collect all your problems (in a
single folder organized by week) and use the quality of the solutions
present in your folder to help asses borderline performances.)

**Exams**:
Both the exams will be take home. The exams will be about the length
of a homework assignment and you will be expected to attempt the entire
exam using only your text, your class notes, and your instructor for
help. You will
receive the first exam on Wednesday February 14 and it will be due at
class time on Monday February 19.
After the exam is turned in, you will be assigned one problem from it to
write up an
accurate solution to which will be posted on the web site, and then you
will present this problem during the "x-session
period". The second exam will
be your final exam.

**Honor policy**:
Collaboration is encouraged during the process of
thinking about and writing up homework problems.
No collaboration of any form is acceptable during exams, and (expect when
explicitly stated on the exam) the use of any references other than your
class notes and our book is not acceptable.

**Prerequisites**:
You should be comfortable with
understanding and producing mathematical
proofs.

**Students with disabilities**: I encourage students with
disabilities, including "invisible" disabilities like chronic diseases
and learning disabilities, to discuss with me any
appropriate accommodations that might be helpful.
