Seminar Geometric Methods in Mathematics
This is the research seminar of Uli (Prof. Dr. Ulrich Krähmer) and his group. The talks cover topics in homological algebra and category theory, noncommutative algebra and geometry, or Hopf algebras and their generalisations. The target audience consists of PhD and MSc students.
Unless otherwise indicated, the seminar takes place in WIL B216 every Friday at 3:00 PM (CEST/CET) and we usually stream them on BigBlueButton: https://bbb.tu-dresden.de/b/ulr-ha4-xul-uoo.
