A nonlocal modification of geometry at the Planck scale might be necessary for a consistent formulation of quantum gravity. With this workshop we aim at reviewing the most promising current approaches, while focusing on open problems, and discussing new perspectives and strategies. The programme will include time for discussion sessions and collaborations.
This Conference is part of the program "Planck Scale Physics: a rigorous approach to spacetime quantisation", which has been awarded a SISSA grant. We are also indebted with the sector of Mathematical Physics of SISSA for its contribution.
