Lectures in the Winter Semester 2017/2018

Due to the rather broad spectrum of topics within the IMPRS, the curriculum consists of a core curriculum to be attended by all students and a variety of more specialized lectures and courses. The heart of our teaching program certainly is the Ringvorlesung. Each semester the Ringvorlesung focuses on one field and is usually delivered by three scientific members of the IMPRS who introduce three different approaches and visions within this field.
