||On a double-sided sheet of paper to turn in,
write up a review containing all of the topology
definitions, examples, and statements
of results that we covered in class. Short-hand abbreviations, keywords,
pictures, creative ways of conveying the ideas
are fine as long as you understand them.
Begin working on the exercises due next week

of closed sets and prepare to share what you read.
Set theory exercise as assigned in class.
|2 Mar - Tues
||Download, order, or obtain from the library and web the references
we have corresponded about regarding your final project.
In addition, go to the library, and look at the
Handbook of the history of general topology
Charles E. Aull, R. Lowen, 1997
QA611.A3 H36 1997 (multivolume works)
Look through these to check for history of your topic, and look
at the nearby books too.
Also search the print copies of the Historia Mathematica
journals (Bound: v.3(1976)-v.31(2004) (Lower Mezzanine))
Prepare to report back on what you found.

||Each person in the class will choose a different proof from class
or the previous exercise sets - message me your choice on ASULearn to
obtain approval and I will list them here.
In latex, type up your proof.
Turn in your source code as well as your compiled version, which must
distinguish your proof as your own. The purpose of this assignment
is to revisit some of the previous proofs in order to improve them
and your understanding of them, and also to try latex.

Sample Proof 1: The square metric equals the
Euclidean metric on R2.
Sample Proof 2: Topology Exercises #5.
Use of math symbols and equations
Additional latex symbols
To run LaTex on campus Macs, use TexShop.
To run LaTeX on campus PCs, you need to download TeXworks-setup, a free 'front-end' for LaTeX.
Click on the 'TeXworks-setup' link above to download the installer. Run the installer, then launch TeXworks. Installing TeXworks on a 'thumb drive' lets you use it on any campus PC without reinstalling each time.

share what you read about, including related definitions and theorems
(but not the proofs).
In addition, reflect on the similarities and differences.
|19 Jan - Tues
Read p. 12-13 in Munkres.
You may work alone or in a group of up to 3 people and turn in 1 per
group. Make copies of your work so that you are prepared to present any
of the exercises after you turn it in.
1. Choose 1 of Mendelson p. 6 #1a or 1b
2. Mendelson p. 11 #3
3. Let f:A → B be a function and C1,C2 &sube A.
Prove that f(C1 &cap C2) &sube
f(C1) &cap f(C2). In addition, give an example to show that equality fails.
Finally, what assumption do we need to make about f - one-to-one, onto, or
both - in order to ensure equality holds? Prove your answer.

(It often helps to draw a picture).
3. Let Tn=[-1/n,1 + 1/n]. Find the intersection ∩ n=2 to infinity of Tn.
4. (Graduate Problem)
No path can be found between the seven Konigsberg (now Kaliningrad, in Russia)
bridges, since this is exactly what Euler proved. Search on the web or in
a library, find useful references, and summarize why no such path
can be found.
