Conformal geometry and its generalisations emerge in many different areas, including CFT, (flat space) holography, boundary calculus and asymptotic symmetries, as well as twistor methods in field theory. Remarkably, all these themes become intertwined around conformal higher spin (CHS) gravities which are higher spin extensions of conformal (Weyl) gravities, and these theories suggest a vast generalisation of conformal geometry. In particular, CHS gravities generate various conformally-invariant operators and are closely related to conformal anomalies. Moreover, CHS fields can be identified as boundary values of massless fields in AdS space via Feffermann-Graham expansion. In low dimensions, another kind of geometry becomes important, namely twistor geometry, which is crucial for studying self-dual (conformal) theories, including higher spin gravities. The purpose of this workshop is to bring together mathematicians and physicists interested in these research directions.

How to reach the conference venue
  • Direct trains from Zaventem airport to Mons are available every hour. You only have to be careful to look for trains directed to Bergen, which is the Dutch name of Mons; alternatively, you can reach the station Brussels Midi and take a train to Mons;
  • Charleroi airport is connected to Mons by a shuttle bus (bus schedule);
  • Trains from Brussels to Mons are running every half an hour, starting around h:25 and h:56 from Midi station (please crosscheck the train schedule!);
  • The workshop will take place in the UMONS campus “Plaine de Nimy”, that can be reached from Mons train station in 20/25 minutes by walk (see the precise address below). A limited number of blue-bikes is also available at the train station;
  • The talks will take place in the building De Vinci (map of the campus).
