The seminar will take place in an online format. For detailed instructions, please vist the Friedolin and MOODLE pages of the course. Very briefly, the course will be composed of the summary of one special topic from the list of the proposed topics. Every participant is requested to upload a PPT file and a short (max 20 min) videocast about that topic to the cloud of the FSU Jena. In order to replace the physical interactions we opened Chatforums on MOODLE where you must discuss the open topics. If you are unable to prepare the requested videocast you can also fulfill the requirements of the seminar by preparing a 10 pages long written Hausarbeit. Unfortunately, the short introductory talks by Prof Kovács will not take place this semester. Instead, we uploaded the slides of these lectures to MOODLE and opened various forms of interactions via chats and forums.
