Corona news:

There will be an initial (short) online zoom meeting on
Monday, April 12th
11 am
discussing the modes of operation of the lecture and exercises.

In order to send the link of the meeting to you please send me an eMail
Sunday, April 11th,

if you intend to attend the lecture.

Thank you.

    4. Hamilton and cluster operators in diagrammatic form
    5. contractions and CC equations in diagrammatic form

Please note that the lecture contents of TCA in winter and summer terms differ. The winter term’s subjects are more fundamental and basic.

If you are free (of scheduling issues) to choose I recommend attending the winter term’s lecture. However, the summer term’s lecture is self contained and may be attended independently. Both lectures are (offline) mostly black board type lectures. In the winter semester there is also a number of computer animated illustrations.

In any case you should have a theoretical interest and no reservations about math...

Many students before attended one term as TCA and the other as S-module.
