Advanced Seminar on Relativity and Cosmology14756.5003  Winter term 2019/20Thursdays,
10:00–11:30 Advanced seminar within the Primary Area of Specialization GRQFT Contact person: Nick Kwidzinski (2.02 new building ThP) ContentsTopics from the lecture courses on Relativity and Cosmology I and II.It is recommended to give a blackboard talk. But you can, of course, use the projector to show graphs and images. The talk time should not exceed 60 minutes in order to allow for questions and discussions.
