>>10264851It's just a spiral bound linear algebra textbook that our school uses for our math major linear. It's mostly based on the University of Michigan's MATH 217 (they use Bretscher but that book is crap). Students seem to like it.
We (by "we" I mean myself and a post-doc) are working on a second one that will be a better Introduction to Riemann-Roch Algebra than Fulton-Lang, but that's a long way off, especially since we're both busy with our research projects right now.
