Today's lecture is cancelled

I feel obliged to cancel today's lecture as my voice has steadily gone away. I could probably offer something that one could call "a lecture" being very optimistic and it was hard to make the decision, but you deserve a real lecture, not just any mediocre lecture!

I had prepared to go through the following exercises today: 2.1, 2.2, 2.3, 2.4, 3.3, 3.4, 3.6, 3.11, 3.18, 3.19, 4.26 and 4.27.

Meet together, you may sit in the auditorium if it is available or somewhere else. Discuss and solve the exercises and send me an e-mail if you have questions! I can barely talk, but I can type!

See you on Monday. My deepest voiceless apologies for this short notice.
