Abstract Algebra A/B, Math 420/425
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
- Seeing students.
- Commenting on homework.
- Getting ready for class.
- Doing mathematics.
- Seeing my family.
- Being present on, and experiencing, the world God created.
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.
- The Greek and German alphabets.
- The first few sections of Herstein's
book. I won't copy future sections, but this gives you a start if
you don't have the book yet.
- Old Solutions to many of the
problems in Chapter 1.
