The Friday Fish is a weekly seminar on differential geometry that has been taking place in Utrecht since 2004. It started as an activity for researchers, PhD candidates, and visitors in the field of Poisson geometry (partially explaining the name). One of its core aims from the outset was to provide a platform for young mathematicians to present their research, learn new ideas, and to broaden their network. Whereas our goals regarding young researchers have remained the same over time, the focus on Poisson geometry has progressively broadened to include the study of other geometric structures. At the moment, the seminar deals with differential geometry and topology in general.
