Doctoral seminar

During the Fall Semester 2021/2022, the seminar is organized by Robert Šámal. Contact me (at samal@iuuk....) if you have any question.

The participants of the seminar present papers of general interest from mathematics and theoretical cs. The articles are selected by the seminar organizers and/or advisors of participating PhD students. The speaker's task is to read and understand the whole paper, then present the main/most interesting parts of it. For each paper there is "mentor" available who will be glad to help you with understanding the paper. Please do explain motivation and "big picture" -- but don't stop there, we want to see the proof, or at least part of it (and overview of the other parts).

The person presenting a paper is also responsible for preparing a one- to two-page summary (handout) before the seminar. Please send an electronic version by email to samal@iuuk... (at least an hour before the seminar starts, I will bring a physical copy for everyone).

A summary of the proposed articles is available at a special page. More papers will be added soon. Articles from other sources are welcome, but consult them please with the seminar organizers.

Announcements are sent out via mailing list dokt-seminar-l@kam. If you wish to subscribe, visit the archive or change your options, see the mailing list webpage.
