GCS Postdoc and Student Colloquium
Brief description: The goal of this online colloquium is to bring together postdocs and students associated to the Simons collaboration on Global Categorical Symmetries. We hope to create a common vocabulary between mathematicians and physicists working on categorical symmetries, keep up with current developments in the field, and introduce the most important ideas and definitions. The colloquium is also supposed to strengthen the connection between the younger members of the collaboration and give them a place to discuss their (ongoing) research in an informal environment.
Format: The colloquium will usually consist of three parts
an accessible background (possibly tag-team) talk created to be accessible for graduate students in math or physics
a break for discussion and rest
a second talk, slightly shorter with more of a focus on research results but still broadly accessible to an interdisciplinary audience
