Exercises: Ross Ogilvie – r.ogilvie uni-mannheim.de

tuesday 3:30 pm – 5:00 pm in B6 Teil A 101 / 301.

The first tutorial will mostly consider background material and you do not have to submit the first exercise sheet. Thereafter, please email your exercises by 12:00 the day before the tutorial, so I (Ross) can mark them and give feedback. A minimum of 50% of the exercise points is necessary to be admitted to the exam.

Exercise Sheets:

Sheet 1Solutions

Sheet 2Solutions – B6 Teil A 101 – Transport Eqn, Burger's Eqn

Sheet 3Solutions – B6 Teil A 101- There is a justification of the entropy condition on physical grounds in Evans' book Partial Differential Equations pg 142–3.

Sheet 4Solutions – B6 Teil A 301 – All the points from the last exercise are to be considered as bonus points, so the sheet was out of 19. Here is a scan of the additional exercises we did in class. The quasi-linear PDE whose characteristics we looked at in (x1,x2,z) space is here. I made it so you can put in any function as the initial condition. Observe the crossing of the characteristics is when the surface is not a graph over (x1,x2).

Sheet 5Solutions – B6 Teil A 101 – Compact Support, Convolution

For your interest, here are two papers about PDE theory broadly: a historical perspective and on the unity of the subject.
