Note added 19 Jul 2002: all PostScript files are now compressed using Gzip to save space.

- 3: should refer to Problem Set 4.
- 7: Assume that K is not L.

Office hours: Monday and Thursday 1-2 PM, or by appointment, or just drop by. If the door is open, come right in; if not, go ahead and knock, but I reserve the right not to answer. I'm usually in my office immediately after lecture, and generally during late morning (before noon) and early afternoon (until 3 PM). I'm often at tea in 1015 Evans from 3 to 4 PM. I also will respond to questions by email, usually even over the weekend.

documentation; the same documentation can also be found in the folder
`/usr/local/Magma` on the department network.
Print copies of the Magma manual can also be found in
room 708S (adjoining the computer cluster); please do not remove these.

Magma is not free software, but the math department has a site license. This means it is possible for department affiliates (or non-affiliates enrolled in a course using the program) to install Magma on their own computers. See Paulo Ney de Souza or one of the other computer staffers on the 9th floor for details.

Other books worth looking at for various reasons are:

- Borevich and Shafarevich, Number Theory
- Cassels and Fröhlich, Algebraic Number Theory (just the early chapters, for starters)
- Fröhlich and Taylor, Algebraic Number Theory
- Ireland and Rosen, A Classical Introduction to Modern Number Theory (for background)
- Janusz, Algebraic Number Fields
- Marcus, Number Fields (lots of examples)
- Pollard and Diamond, The Theory of Algebraic Numbers (assumes minimal prerequisites)

If you're shopping for an advisor in number theory, check out the Web pages of Robert Coleman, Hendrik Lenstra, Arthur Ogus, Bjorn Poonen, Ken Ribet, and Paul Vojta.

Some more possibly useful links:

- J.S. Milne has printable notes from a variety of courses, including Algebraic Number Theory.
- The Number Theory Web is the home of all things number-theoretic on the Web.
