Welcome to the HT 2012 version of Nonlinear Systems

The lectures for this course are Mondays at 4pm and Thursdays at 11am in room L1.

I have now posted the typed lecture notes and homework sheets for HT 2012. I corrected one typo in the 2nd document of the lecture notes, but otherwise everything is the same as last year.

There will be five sets of classes:

I will teach [class 1] one set of classes in odd weeks (weeks 3,5,7) Friday 2:00 - 3:30 pm in DHSR3. This class will also meet in week 1 of TT, but the time and place cannot be specified until just before TT starts. The TA for this class will be Sofia Piltz.

Wonjung Lee will teach [class 2] a set of classes in even weeks (2,4,6,8) Friday 2:00 - 3:30 pm in DHSR3. The TA for that class will be Andrey Melnik.

Ruth Baker will teach two sets of classes. One of them [class 3] will be DHSR3, Weeks 3,5,7,8, Mondays, 9:30 - 11 am. The other [class 4] will be DHSR3, Weeks 3,5,7,8, Fridays, 3:30 - 5 pm. The TA for class 3 is Marta Sarzynska and the TA for class 4 is Sofia Piltz.

Margarita Schlackow will teach [class 5] the final set of classes. It will meet in even weeks (2,4,6,8) Friday 10:00 - 11:30 am in DHSR2. The TA will be Marta Sarzynska.


Friday classes in week N will have homework due at 10:00 am on Wednesday of week N. The Monday class in week N will have homework due at 10:00 am on Friday of week N - 1. Boxes will magically appear in the basement of the Mathematical Institute.

Consultation Sessions

The following consultation sessions have been scheduled for Trinity Term:


Monday, week 2, 10 am - noon: L3 [Me; covers 2010 mock exam]

Wednesday, week 2, 11 am - noon: DHSR1 [Me; drop in]

Monday, week 3, 10 am - noon: L3 [Me; covers 2010 exam]


Chong Luo will be holding consultation sessions at 13:00-14:00 for the dates May 3, 17, 31 (i.e., Tuesday of weeks 1,3, and 5), and also June 1, 8 (i.e., Wednesday of weeks 5 and 6). These sessions will all take place in DHSR2.

Kostas Zygalakis will be holding consultation sessions on Mondays from 3 - 5 pm in weeks 4 and 5 and on Wednesday from 4 - 5 pm in week 4. These sessions will all take place in DHSR3.

Class Times for Odd-Week Classes (TT, week 1).

The odd-week classes for week 1 of TT will occur at the same time as they have been for this term. The times and locations are as follows:

Monday, 2 - 3.30 pm, DHSR3 (Luo + Webber)

Thursday, 10.30 - 12 noon, DHSR2 (Porter + Cherif)

Friday, 10.30 - 12 noon, DHSR3 (Zygalakis + Cherif)

Solution Sheet 3 posted

I have posted the solutions for the 3rd homework assignment.

Which Extra Topic(s)?

This year, it looks like there will be some time in the last couple of lectures to cover some 'extra topics', which can in principle differ from year to year.

If there are any in which any of you have particular interest, please either comment here or drop me a line.

I haven't yet made these lectures, so let me know what interests you.

Solution Sheet 2 posted

I have posted the answers to the second problem sheet.

Solution Sheet 1 posted

I have posted solution sheet 1.

Matlab Class

Kostas Zygalakis will be holding a class on Matlab in Week 3.

It will take place in room L2 in the Mathematical Institute on Friday (4 Feb) from 4:30 - 6 pm. It will be necessary bring laptops on which Matlab is installed.

Matlab Code on MI Website for B8b

I have now specified that the Matlab guide for B8b is from an old version of the course (taught by someone else). I have now made the code referenced therein publicly available in case you find it helpful, but of course it is necessarily user-beware because somebody else wrote this code. The code is from an old version of the course and uses different notation, etc.
