with suggested solutions (in Norwegian) is available at the
exam collection page.
Let me know if you find any errors in the solution.
D. W. Jordan & P. Smith: Non-linear ordinary differential equations:
An introduction to dynamical systems, Fourth Edition,
Oxford University Press 2007, ISBN-13 978-0-19-920824-1.
Ch. 1, 2, 3, 8, 10, 11, 12.1–4, 13.1 and Appendix A. Except 1.6, 3.3, 3.5, uniform stability i 8.3–8.4,
all details concerning topographical systems in Ch. 10
(i.e., most of 10.2–10.4), and 10.11.
I don't understand Theorem 10.10 (p. 351 (362 in the third edition)),
so skip that.
You will note that my notes overlap quite a bit with the book,
in which case you may choose which text to read.
(But note that the statement of the Poincaré–Bendixson
theorem in the book is wrong.)
