Jim Hefferon, PhD

Professor of Mathematics

B.S., M.S., Ph.D. University of Connecticut

My background is in the theory of computation. In addition, I administer the CTAN archive of software for the TeX typesetting system at www.ctan.org.

Courses I Teach:

  • Calculus
  • Numerical Methods
  • Statistics
  • Theory of Computing

Some of my summers in college were spent working at Perkin-Elmer in Danbury, Connecticut, in part on the Hubble Space Telescope (I never touched the mirror, I swear!). After going to UConn for much too long, I taught at Union College in Schenectady for three years and then had a year at the Groton branch of UConn and in industry, working on programs for submarines. I came to Saint Michael's in 1990. 

Recent Scholarly Achievements: I co-wrote The TeX family in 2009 for the American Mathematical Society's Notices. I gave the invited address at the EuroBacho TeX 2007 conference in Tama Brodzka, Poland, on "An Experimental Upload System for CTAN."

I am the author of a Linear Algebra undergraduate textbook. Here is a downloadable copy:

Linear Algebra.

Briefly, this text features standard coverage (linear reduction, vector spaces, linear maps, determinants, and eigenvalues), proves things but carefully covers the needed computations also, and has extensive exercises, all with worked-problem answers. It has been class-tested a few times, and is suitable for a person to use as a main text in a class, or as a supplemental book, or for self-study. I think it's pretty good!

Life Off Campus:

Outside Saint Michael's I like to jog, do ham radio (KE1AZ) and spend much time hacking around with Linux. My Erdös-Bacon number is 7.
