**Welcome to the class!
Class announcements and useful documents will appear here. New
material will be added at the top. Make it a habit to look here.**

**I'm going to try keeping
the lecture notes and an indication of the current assignments at the
top of the page: watch for other things that might appear below.**

**Here
are the lecture notes. I notice that there are some good note readers
out there, catching typos and other slips...keep it up! The notes
have been updated 4/28/2014, with the completion of the n=3 case of
Fermat's Last Theorem. I have not come up with creative thoughts
about homework related to that topic, so I will leave it to Dr.
Scheepers to give you your next homework assignment. It was
interesting to lecture it; do please read my proof, as in at least
one place it differs noticeably from my lecture (though overall the
plan is the same, including the strange order). I was unable to post
the Macys paper, but the essence of it is in the notes.**

**I will not be caught up
on homework grading tomorrow (I have been ambushed by a trip to the
mountains with my Significant Other followed immediately by the
Passover holiday) but I should have a new lecture out and a new
homework assignment for you to have fun with.**

**I have found ingredients
for the proof of the FLT with n=3. It is quite formidable: it remains
to be seen whether I am brave enough to present it!**

**Here
is my Euclidean algorithm spreadsheet calculator.**

**The Assignment posed
4/16/2014 and due 4/25/2014: Some problems from the other book I used
for the Rabin witness proof, which I will post in a file here;
30.1, 30.2, 30.3, 31.1, 31.2, 31.3**

**I am posting an
assignment now (4/6/2014, Sunday) though I have not yet updated the
notes. I hope I will have those ready by class Wednesday, and of
course what I said did (mostly) follow the book. Since I am posting
it Sunday the 6**^{th}**,
I am making it due Wednesday the 16**^{th}**
****rather than Friday
the 11**^{th}**.
**

**The Assignment: 21.2 (if
I did not assign it already), 23.2, 23.3 optional, 23.4, 23.5; 24.1a
(exploratory), 24.3 (do this as much by hand as possible), 24.4
(ditto), 24.8 (optional, encouraged, and I'll probably eventually
post one), 25.1, 25.2, 25.6 (I don't know the answer...) It is
possible that I will add a problem or two based on Wednesday's
lecture.**

**I would still like to
see some Secret Message traffic – three RSA keys are up now...**

first one:**

**My
office is MB240A. I have M287 (Communication in Mathematics) 12-2 pm
T/Th and M406 (Number Theory) 10:30-11:45 am WF. I have logic seminar
on Tuesdays at 2 pm. My official office hours will be 10:30-11:45
T/Th and 3:15-4:45 T/W/Th/F effective immediately. Students should be
warned that afternoon department meetings or colloquium talks may
cause 3:15 office hours to be cancelled; I will provide notification
of this on my door, and will try to provide other notification online
when I can. I will very likely not be on campus on Mondays; on the
other four weekdays I will usually be on campus from 10:30 (or
possibly earlier) to 5. If I am in my office I will usually be
available to you.**

**Announcement: ****In
the last two weeks of class Dr. Scheepers will teach the class. I
have to have surgery shortly after April 25**^{th}**.
I have decided (subject to change) that a third hour exam will be
administered during the final exam period, rather than a cumulative
final.**

**I
will in any case be awarding your final grades, but I will be out of
sight.**

**Test I will be on Friday
February 21**^{st}**.
See review sheet just below! Your fourth homework set will be
returned graded to you on Wednesday. The coverage of the test
includes the material in Homework 5, so make sure that you are armed
with questions on Wednesday!**

**HERE
is a review sheet for Test I.**

**The test has been
marked. The grade distribution (using a rather esoteric formula) was
100, 93, 72, 70, 65. I'll go over the test tomorrow.**

**Here
is the review sheet for the Test on March 21**^{st}**.**
