In the week June 23-27, 2025 I am attending the conference Integrable Systems and Related Areas organized at the Center for Geometry and Physics, IBS POSTECH, in Pohang, South Korea. At the conference I give a presentation on Maslov S1 bundles, a recent work jointly done with Bohuan Lin (XJTLU) and Holger Waalkens (Groningen). I would like to thank the conference organizers, Alexander Aleksandrov, Anton Alekseev, Sonja Hohloch, Yong-Geun Oh, and Tudor Ratiu for their kind invitation to present my work at this very interesting conference.
