Thanks!

Many thanks to all of you in Lahore. I cherish the time we have had together. Good luck with all that comes next!

Added material

 I have now added the entire file of slides used, as well as solns of all problem sheets.

I will still upload the notes on normal forms, after revising this slightly asap (as I noted this is needed).

Recommended literature (for more advanced material)

For those more interested in the differential geometric approach to qualitative theory, please see

the books by V.I. Arnold (uploaded in the dropbox).

class test Thursday 1:15-2 pm

 The class test concerns the following material:

(1) chapters 1,2,3 of M2AA1notes16

(2) problem sheets 1,2,3

Questions will query your understanding, not your memory.

Model answers for most of the questions on the problem sheets are now provided.

Decoupling principle

 I have uploaded Sadun's text Applied Linear Agebra: the decoupling principle, to the dropbox folder.
