I will emphasize for this class that this is the first time I am teaching it, so I may make changes in midstream if it seems to be necessary.

In general terms, the best way to reach me is by email. `holmes@math.boisestate.edu` will reach me; replies will come from `rholmes@boisestate.edu` (and of course you can use that address too). I read my email constantly (on weekends too) and try to respond reasonably promptly.

Here is the math department catalog language about the course:

MATH 533 ORDINARY DIFFERENTIAL EQUATIONS (3-0-3)(S)(Odd years). Theory of linear and nonlinear ordinary differential equations and their systems, including Dynamical systems theory. Properties of solutions including existence, uniqueness, asymptotic behavior, stability, singularities and boundedness. PREREQ: MATH 333.

We meet in Mathematics room 139 TTh from 1:30 pm to 2:45 pm.

Our "final exam" (it will actually be the last hour exam) will be on Thursday May 4, 12:30--2:30 pm in this room.

I am teaching this course for the first time; it may be an adventure! I have Dr. Zubik-Kowal's notes for the class, and I have ordered the text which they are based on:

*An Introduction to Ordinary Differential Equations* (Universitext) by Ravi P. Agarwal and Donal O'Regan, ISBN-13: 978-0387712758,
ISBN-10: 0387712755

I would buy this at the bookstore if I were you: consequences of delay of possession of the textbook due to ordering it online and of having the wrong version are really your own problem, and the accommodations I will offer are limited.

Problem sets due after an exam **are** fair game for that exam if they were assigned two sessions before the exam, so that you had a chance to ask questions. (Such a problem set will probably have been assigned on the Thursday before the exam, which is likely to be on Thursday, and will be due on the Tuesday after the exam; I do not make homework due at exams). I will **not** usually describe homework sets in class: make sure that you look on the class announcements page regularly!!!

Your total homework grade will count as one test grade. I am planning to give four hour exams, the last one to be held in the final exam period. Dates are to be announced. The weights of the hour exams and the homework grade will be the same; the lowest of these grades will probably be dropped or reduced in weight. Adjustments of this scheme are possible: for example the weight of the homework might be increased to two tests if I thought this helpful.

Individual exams will generally be marked in such a way that the average or median is somewhere around 75 percent (it may be above this if you all do well, or below it if I have a low opinion of class performance). 90 = A, 80 = B, 70 = C, 60 = D. 50 = F as usual. I do not award grades of A+ or C- under any circumstances. I only award the other +/- grades under special circumstances: no point total earns such a grade and I will not negotiate such a grade. You should expect that your grade will be an unqualified letter.

On hour exams you are allowed the use of your writing instrument, your test paper, and a calculator if required. I will supply scratch paper if it is needed. I will supply information in advance of any exam as to what calculator will be needed or permitted.

Please ensure that your cell phone does not ring in class. Your cell phone must be inaccessible to you during an exam.

You may not listen to a portable music player during an exam. This is self-evident, but I once had a fight with a student about it, so I always say it!
