organized by Oleksiy Sukaylo and Julian Wendt.
There is a weekly seminar mainly organized by and intended for PhD students of the department of mathematics and computer science. During the lecture period, it takes place
on Mondays from 12.15 to 1.45 p.m., SR 3517, Ernst-Abbe-Platz 2
Currently the seminar moved online, please contact the organizers for the details to take part.
This seminar aims to present different research areas and to animate the doctoral life. The contributed talks should explain basic ideas of the achieved work avoiding complex details but communicating main intensions of the doctoral research to other students. Feel free to give a talk and join us. We also very welcome master students and postdocs who are interested to join.
