Grade
Breakdown: | Class Participation - 5%, Midterm - 30%, Homework - 35%, Final Exam - 30%. The
grading scale will be the standard 10 percentage point scale, so that a final
score of 93 or higher is an A, 90-92 is an A-, 87-89 is a B+, 83-86 is a
B, 80-82 is a B-, 77-79 is a C+, 73-76 is a C, 70-72 is a C-, etc. |
| Attendance & Lecture Policy: | It is expected that you attend all
lectures, with exceptions minimized. It is greatly appreciated when you
are on time. Please do your best to stay awake and attentive during
lecture, please do not email or text during lecture, and keep all cell
phones/hand held devices/laptops put away during lecture. While it is
understandable that you may miss a lecture here and there, or be sleepy in
class once in awhile, repeated absences, late arrivals, naps, or general
non-attentiveness will negatively affect your class participation score.

| Prerequisites: | Math 311 Elementary Analysis. By the end of the
course, we will also need a few very basic notions from Math 307 Abstract
Algebra (essentially, if you know what groups and homomorphisms are by
November, you will be fine). |

Syllabus:
Topology is a tool used to study local information of a space. You have
seen a very important example of topology in Math 311 Elementary Analysis,
namely, the metric topology. Local information of the real line is studied by
studying neighborhoods of points. A large part of this class will be the study
of General or Point-set Topology, and we will generalize many of
the notions and results obtained in Math 311 to a larger class of spaces.
Specifically, we will cover essentially all of Sections 12-33 (and Sec. 36, 37) of the text,
where Chapter 2 (Sec. 12-22) and Chapter 3 (Sec. 23-29) will develop notions
such as continuity, connectedness, and compactness, for arbitrary topological
spaces. We will conclude our study of general topology by proving two
relatively deep results: The Urysohn Lemma (Sec. 33), which we will apply to
introduce imbeddings of manifolds (Sec. 36), and The Tychonoff Theorem
(Sec. 37), which is an important result on products of compact spaces.
After concluding the above topics on general topology, we will begin an
introduction to Algebraic Topology. The main idea of algebraic topology
is to construct an algebraic object (such as a group) based on the structure of
a topological space, which may be used to compare two topological spaces. We
will get as far as we can in Chapter 9 of the book, which gives the
construction of The Fundamental Group of a topological space.
Dates & Course Announcements:
Midterm and Final Exams:
There will be one midterm, and it will be a take-home midterm. The final exam
will be timed. The midterm and the final will each count as 30% of your final
grade. The final exam will be on Mon, Dec 16, from 9 AM until noon.

- (9/9) I had to slighlty shift my Tues, Sept 10 office hours to 10-11:30 AM
(rather than 9:30-11 AM). I apologize for any inconvenience this may cause.
- (9/13) I have set my weekly office hours for the semester as: Mon 10-11
and 4-5, Wed 10-11 and 3-4:30, Thurs 10-12.
- (10/7) My office hours this Wed afternoon (10/9) have to be shifted
earlier, and will be 2:15-3:45 (instead of 3-4:30).
- (10/16) Please note that HW #7 is due on Wed, Oct 23 (instead of the usual
Friday). The take-home midterm will be handed out on Mon, Oct 28, and will
be due on Mon, Nov 4.
- (11/4) My afternoon office hours today, Nov 4, will be 3-4 instead of 4-5.
- (12/6) I will have your last homework graded and ready for you to pick up
in my office on Monday, Dec 9. You can come pick it up any time during the
hours 12-2 or 3-5 in my office (Jones 130).
- (12/6) During the first week of finals (prior to our final) I will be available in my office on the following days and
times: Mon, Dec 9, 12-2 and 3-5; Thurs, Dec 12, 9-11, 12-2, and 3-5; Fri,
Dec 13, 9-11, 12-2, and 3-4:45.
- (12/12) My office hours on Fri, Dec 13, are ending at 4:45 instead of 5.
Homework:
Homework problems will be a very important
part of the course, and there will be homework assigned almost every week (other than
the week of the midterm). Completion of all homework problems is required, and your
grade on a homework assignment will be based on completeness, as well as on the
details of the solutions of the problems graded. Proofs should be written
carefully and neatly, with attention paid to the completeness of your argument. Individual homework
assignments should be completed by the student alone, although I am always open
for questions, either in office hours or by email. You should not, under any
circumstances, attempt to look up solutions or hints to problems online. I
will consider this plagiarism, an honor offense.
Homework is due at the beginning of
class on the due date of the assignment. Late homework will be marked off 20%
for every day late (10% off if it is turned in after the beginning of class,
but it is in my hands on the day it is due). Homework turned in after class on the due date is
considered one day late, and the next weekday after that 2 days late, and so on. Everything
is easier, of course, if you turn in the homework on time!
Homework scores will each be out of 50 points. Your lowest homework score of
the semester will
be dropped.

Math Major Writing Requirement (Math 300):
If you are a math major, and you would like to complete your major writing
requirement through a writing assignment in this class, please let me know in
the first week of class. This writing assignment will not count towards your
grade in this class, but will rather just serve as your Major Writing
Requirement. If you decide to do this, you must write your paper on a topic in
Topology approved by me, and you must keep to a schedule of turning in
drafts that is set at the beginning of the semester in order to get credit.
You are also encouraged to sign up for Math 300 during this semester if you
fulfill the writing requirement through this class.
