Kurslitteratur

Rudin är slut på förlaget (men kan köpas t.ex. på www.amazon.co.uk). Jag kommer därför att använda Lax som huvudbok och bara använda Rudin för vissa kompletteringar.

En kort engelsk-svensk ordlista finns nedan.

Homework

Three homework assignments will be given. These form part of the examination. Correct solutions will give bonus points on the exam (up to 3 bonus points per set, i.e., total maximum 9). Solutions can be given to me at lectures, or in my mailbox at Ångström (floor 4), at the latest on the days shown below.
  1. 16 September.
  2. 6 October (changed).
  3. 12 October.
