- Notes and pages on topics in math
- Math-related organizations and Web sites
- Free mathematical software

*Note:* I only link to pages that I use
myself. If you want a page with dozens of math-related links, you could
just do a Google search on "math"; I'm being selective to
avoid overwhelming people with too many choices. But the fact that I
haven't linked to a page doesn't mean I think badly of it.

Some of the notes are web pages, usually accompanied by PDF (Adobe Acrobat) files for printing. Some of the older notes are in PostScript format; I plan to convert them to web pages with PDF as time permits.

Please read the PostScript help file before you download any of the notes in PostScript format.

I appreciate hearing about mistakes, which I'll correct as soon as I can. Some of the notes are very incomplete; there may be a few worked-out examples, with little exposition.

- Basic algebra and trigonometry
- Calculus
- Math proof
- Linear algebra
- Notes on linear algebra
- Functions for performing row and column operations, finding the convolution of two functions, and computing the exponential of a matrix.(matrixop.m [3175 bytes]; Mathematica package).

- Abstract algebra
- Differential equations
- Notes on differential equations (PostScript)
- The existence and uniqueness theorem for ordinary differential equations via Picard iteration (picard.ma [37K]; Mathematica 2.2 Notebook).
- Functions for performing row and column operations, finding the convolution of two functions, and computing the exponential of a matrix.(matrixop.m [3175 bytes]; Mathematica package).

- Elementary number theory
- Notes on elementary number theory
- (GIMPS) The Great Internet Mersenne Prime Search. Use your computer to help find the next Mersenne prime.

- Topology

The *Mathematica Notebooks* require at least Mathematica 2.1.

- The American Mathematical Society is a professional organization whose primary focus is on research.
- The Mathematical Association of America is a professional organization whose primary focus is on teaching.
- The TeX Users Group
is devoted to TeX, a computer typesetting system. TeX is
the
*de facto*standard for technical typesetting among professional mathematicians. - The Front for the Mathematics ArXiv is the largest preprint server for the mathematical sciences.
- The Topology Atlas provides news, publications, and course resources related to topology.

- Maxima is a GPL-ed symbolic mathematics program. It does (among other things) algebra, calculus, and graphing in 2 and 3 dimensions.
- GAP is a free system for doing computational discrete algebra. It is best known as a tool for doing computational group theory.

(At this point, I think I'm required to remind you that some of the links above take you out of Millersville University Web space, and that we aren't responsible for the content you reach by following those links. If you wind up in the Arabica Coffee Shop on Coventry Road in Cleveland Heights, Ohio, or get kidnapped by aliens in a space ship, it's not our fault.)
