Workshop on the h-principle and beyond

Organizers: Kai Cieliebak, Camillo De Lellis, Yakov Eliashberg, Emmy Murphy, László Székelyhidi Jr.

The aim of the workshop was to bring together researchers working in different areas of geometry, dynamical systems, and PDEs which have been and can potentially be affected by the most recent developments in the h-principle.

Confirmed speakers:  Daniel Alvarez-Gavela (MIT), Melanie Bertelson (Univ Brussels), Vincent Borrelli (University of Lyon), Lev Buhovsky (Tel Aviv University), Dimitri Burago (Penn State University), Alvaro Del Pino Gomez (University of Utrecht), Mike Freedman (Microsoft), Bernhard Hanke (University of Augsburg), Jonas Hirsch (University of Leipzig), Boris Khesin (University of Toronto), Oleg Lazarev (University of Massachusets, Boston), Eva Miranda (UPC), Yoshihiko Mitsumatsu (Chuo University), Sam Nariman (Purdue University), Danie Peralta Salas (ICMAT), Francisco Presas Mata (ICMAT), Melanie Theilliere (University of Luxemborg), Francisco Torres de Lizaur (University of Toronto)
