Ch. II: 1 (to 1.4), 2, 4 (to 4.9), 5 (only 5.4, 5.8, 5.9)
Ch. III: 1-3, 5-6, 12, 14.

Homework

Three homework assignments will be given. These form part of the examination, and should be solved individually. Correct solutions will give bonus points on the exam (up to 2 bonus points per set, i.e., total maximum 6). 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. 27 February.
  2. 5 March.
  3. 12 March.
