I figured the students would appreciate these DE notes before the end of the semester (and perhaps before the second midterm) so I put up what I have from the notes so far. With obvious warnings of course. The link is http://www.math.uiuc.edu/~jlebl/286notes/ (license is cc-by-sa, so freely available and usable). They keep changing frequently and are full of typos still.
That brings me to my matrix theory notes. Hmmm. I think I’ll make those readable for the fall semester as I may end up teaching that again. So no point in polishing those. Now as to my SCV notes plan, I may have to postpone this.
