As an audience
Before attending a talk. Check out the title/abstract and mark the words that you do not understand (yet).
During the talk. Make some notes, including keywords of definitions or theorems that you do not fully understand.
After the talk. Look up the keywords and learn what they are.
As a speaker
It is better to be slow and clear than fast but vague---if you need more time, we may postpone the next speaker.
Find corresponding proofs if not provided---see the references of the book.
It is okay to have something not understood---but please make some effort to understand as much as possible and identify the part that you don't understand.
Be prepared by the scheduled time, though the schedule might change.
We follow the regular venue and time below; if there is any change, it will be announced through email.
Venue: SC4013
Time: Wednesday 10:10 ~ 12:00
