This spring Rob is teaching honors Differential
Geometry of Curves & Surfaces (Math 563H).
Here is the (quick-loading, even on a slow connection) ASCII file for Math 563H (Curves
and Surfaces) topics & problems .
Rob is also serving as course chair for, and teaching both (a double) section 4 and (a single) section 7 of Introduction
to Linear Algebra (Math 235).
Here is the (again, ASCII) Math 235 (Linear
Algebra) homework schedule for Rob's sections.
Here's a link to Math 235 WeBWorK.
As in the past, instructors will follow these Math 235
(Linear Algebra) common guidelines.
NEWSFLASH!!!!!!!!!!!!!!!!
WebWorK is going to be working soon!
For you hardcore linear algebraists: the usual multiplication algorithm has complexity O(n^3) for n x n matrices; here's a recent paper on the latest complexity bound: O(n^2.3726...)! (Conjecture: O(n^2) is best.)

Last fall (2011) Rob taught (a double) section 2 of Introduction
to Linear Algebra (Math 235), with links to:

Last spring (2011) Rob taught the computational linear algebra (Math313/513-CS513) course while on
sabbatical at Penn, and last fall he taught -- you guessed it! -- Introduction
to Linear Algebra (Math 235) at UMass....
During spring 2010, Rob taught honors Differential
Geometry of Curves & Surfaces (Math 563H) and a double section of
Linear Algebra (Math 235). Here is the ASCII file for Math 563H (Curves
and Surfaces) topics & problems . (Andrew Reiter and Nicky Reyes
are helping to TeX these now, so please stay tuned!)
Because he was the course chair during a semester when all the other
instructors were graduate students, he and the other instructors
established the following Math 235
(Linear Algebra) common guidelines, which may be useful to future
course chairs.
Here's a link to the Fall 2009 Math 235 Practice Midterm and to sketches of answers!

Math 235 Practice Midterm.
Finally, here's the Fall 2009 Math 235 practice final , along with Peter Norman's handwritten answers , a link to an old Math 235 practice final and links to older Math 235 practice finals or even older
Math 235 practice finals, including one similar to our practice final with answers ....
Here are some
Quick
and Dirty Differential Equations notes prepared by Peter Norman
last fall (with a little help from me) for use in Math 235.

During Spring 2009, Rob taught a special version of
Math 462
(Geometry and the Imagination) - please visit here for
the
Math 462 topics and comments! He also taught a (double) section of Math 235
(Linear Algebra).
In Fall 2008, Rob taught a double-section of Math 235 (Linear Algebra).
Rob was on sabbatical in Spring 2008, but he taught back-to-back sections
of Math 235 in Fall 2007 -- Linear Algebra is one of his favorite and most popular classes!
In Spring 2007 Rob taught Math 425
(Advanced Calculus) and a section of Math 235
(Linear Algebra). Here are links to the Math 425
(Advanced Calculus) homework schedule. Also,
please have a look at my colleague Roman Federov's
problems for enrichment and review.
Rob organized the undergraduate TAP seminar (Math 191) during the Fall
2006 semester. It met in GANG (LGRT 1535) at lunchtime most Mondays and some Wednesdays. The following people kindly
contributed to the
2006 TAP
Topics. Many thanks to all of you!

About the photo: Rob's hair is now a little greyer -- and a little
shorter -- in part because he was elected to the Amherst Select Board in
2005 (having also led a concerted and ultimately successful effort to
preserve Amherst Town Meeting :-)!
In academic year 2006-07 Rob again planned to teach a
two-semester course on
Manifolds
(Math 703-4) for graduate students. Due to unforeseen and unfortunate
circumstances, Rob was not be able to offer Math 704 in the spring.
But here is where to find homework problems and informal notes for
that course:
Manifolds I (703) and
Manifolds II
(704), along with older notes from Fall 2002
(703),
Spring 2003 (704) and Spring 2000 (Math 704).
In the Spring 2006 semester Rob taught Advanced
Linear Algebra (Math 545) ; here are the updated problems/notes
for this course. (Please compare with Rob's Spring 2002 advanced linear
algebra problems/notes.)
Rob also pinch-hit all semester for Ordinary
Differential Equations (Math 331) in Spring 2006; here is the Math 331 general
topics list and the Math 331
homework schedule for Rob's section. (This was an ambitious
syllabus, covering more than the other sections did, and not without
some ill-tempered jeers from the bleachers in the final innings -- it
didn't help that Select Board meetings went on till after midnight on
many, many occasions before this early morning course ;)
In the Fall 2005 semester Rob taught
Introduction to Abstract Algebra (Math 411); here are the notes and
homework schedule .
In the Spring 2005 semester Rob was teaching an experimental
version of Geometry and the
Imagination. This was a very popular course, and Rob hopes to
have the opportunity to offer it again soon, perhaps in conjunction
with Math 563 (Differential Geometry of Curves and Surfaces)!
Rob was on sabbatical for 2003-04. During academic year 2002-03 Rob taught a two-semester course on
Manifolds (Math
703-4) for graduate students.
Here is where to find homework problems and notes from that course: Manifolds I (703) and
Manifolds II (704),
along with older notes from my Spring 2000 Math 704.
Rob has taught the basic graduate topology course several times, most recently in Fall 2000,

version of the final Topology exam for Fall 2000.
