Course Information

Course Description

This will be the continuation of 555. I will assume you remember what you've done, but will ``refresh your memory''. But, in fact, we might not need too much from 555. As in 555, you should be familiar with groups, rings, and fields at the undergraduate level. The course will tailored to the students. Depending on the background of the audience, we will be able to cover more or even different topics. In particular, the knowledge of Galois Theory would be beneficial, but it will not be assumed. Also, some knowledge of basic real and complex analysis will be assumed, again on an undergraduate level, but I will give more details on those if needed.

Here are the topics I'd like to cover: Zeta function (over finite fields), basics of Algebraic Number Theory, Dirichlet's Theorem of Primes in Arithmetic Progression, some Diophantine Equations, and basics of Elliptic Curves.

Course Structure

As stated above, I will try to tailor the course to the students. This makes it harder to have a very precise plan, but here is what I hope to cover:

This might be too ambitious. I might skip a few sections in between, or just give an overview in some cases. I find it difficult to really choose much here, as the topics are all very interesting to me, and I am eager to cover them all. But I will try to keep my enthusiasm from overloading you, and you should help me with that.

Homeworks

Homeworks will be assigned after every class and will be posted at the section Homework of this page. No paper copy of the HW assignments will be distributed in class. It is your responsibility to check this page often! Besides HW assignments, other important information will be posted here. (Check the section Important Notes often!)

The HWs will be collected on Thursdays. Each HW will have problems from the previous week (Tuesday and Thursday lectures). The problems to be turned in, as well as due dates, will be clearly posted here. I will suggest a few problems and ask you to turn in two or three problems a week.

It's unlikely I will post solutions, but if you want to see some solution, you can come see me.

In my opinion, doing the HW is one of the most important parts of the learning process, so I strongly recommend you work hard on them.

Also, you should try to come to my office hours if you are having difficulties with the course. I will do my best to help you. Please try to come during my scheduled office hours, but feel free to make an appointment if that would be impossible.

You can check all your scores at Blackboard. (Blackboard will be used only for scores. This is the official site for the course.)

E-Mails

You will have to check your e-mail at least once a week, preferably daily. I will use your e-mail (given to me by the registrar's office) to make announcements. If that is not your preferred address, write me an e-mail letting me know ASAP. I will assume that any message that I sent via e-mail will be read in a week or less, and it will be considered an official communication.

Feedback

I have an On-line Feedback Form where you can anonymously send me your comments and suggestions. I will consider your comments and try to do whatever I can to resolve possible problems before it is too late. So, please, feel free to use it whenever you have any constructive comment or suggestion. (In fact, I would greatly appreciate it.) If you don't want you comments to be anonymous, just send me an e-mail or come by my office and we can discuss the problem.

Additional Bibliography

Since this semester we will do bits of topics that could take a whole semester (or year!) to cover, there are many references, but not a single one (besides our text) which has exactly all we will cover. As usual, at the end of each section it gives references to other texts.

In any case, here are a few standard books:

Legal Issues

Conduct

All students should be familiar and maintain their Academic Integrity: from
Hilltopics 2010/2011, pg. 41:

Academic Integrity

Study, preparation and presentation should involve at all times the student's own work, unless it has been clearly specified that work is to be a team effort. Academic honesty requires that the student present his or her own work in all academic projects, including tests, papers, homework, and class presentation. When incorporating the work of other scholars and writers into a project, the student must accurately cite the source of that work.

All students should follow the Honor Statement: from Hilltopics 2008/2009, pg. 11:

Honor Statement

``An essential feature of The University of Tennessee is a commitment to maintaining an atmosphere of intellectual integrity and academic honesty. As a student of the University, I pledge that I will neither knowingly give nor receive any inappropriate assistance in academic work, thus affirming my own personal commitment to honor and integrity.''

You should also be familiar with the Classroom Behavior Expectations.

Disabilities

Students with disabilities that need special accommodations should contact the Office of Disability Services and bring me the appropriate letter/forms.

Sexual Harassment and Discrimination

For Sexual Harassment and Discrimination information, please visit the Office of Equity and Diversity.

PLEASE, HIT ``REFRESH'' (OR ``RELOAD'') IN YOUR BROWSER WHEN VISITING THIS PAGE!!!!!!! I usually get messages asking for the update in the HW when it has already been updated. Since I change this page often, some times the browser don't see the changes. But, if you hit refresh and there is still problems missing, feel free to write me.

 

If it is already Friday afternoon and there still is a ``More to come'' after the HW assignment due on the coming Thursday, write me an e-mail at lfinotti@utk.edu, and I'll update it and let you know.
