Abstract Algebra A, Math 420
Tim McLarnan

Disclaimer: Welcome to this page, such as it is. I'll try to keep at least some course material accessible here, but the pickings are likely to be pretty slim. I'm at Earlham in significant part because I think the right way to do mathematics and to engage in scholarship is as a member of a community of scholars working together in small groups in person. It's difficult for me to see how that process is enhanced by my taking large amounts of my time producing web pages. Time spent writing web pages is time not spent

  1. Seeing students.
  2. Commenting on homework.
  3. Getting ready for class.
  4. Doing mathematics.
  5. Seeing my family.
  6. Being present on, and experiencing, the world.

My personal sense is that those tasks count more than web pages, and I've normally allocated my time accordingly. I'll probably do the same this semester. Additionally, I don't particularly enjoy working with the web, in part because it has never been, and is not now, an environment that's very friendly to the 2-dimensional language of mathematics.

Now that I've said that, here's what is available on this page:

Printed Resources: Some of these are in PDF format, since using TeX followed by dvipdfm is one of the few paths to decent-looking mathematical text on the web.

  1. The Greek and German alphabets.
